Fixing the ‘Subscribe to continue reading’ Message on Posts

If your posts are presenting the above message to users that are not logged in (can test in a private browser window), there is an easy fix. In the post editor, look for the “Access” metabox within the editor sidebar. Make sure to change the value to “Everyone” from what it is currently set to and update your post. Now your post should be visible to everyone.

I ran into this feature accidentally, the previous post on this site ended up having the access set to “Anyone subscribed” instead of “Everyone”. This went unnoticed by me for several weeks until I ended up visiting while not logged in and noticed the ‘Subscribe to continue reading’ message. Of course, the Access metabox was minimized so it wasn’t immediately clear what was amiss.

Additional Thoughts

While the access feature is neat (if you want to use the various Jetpack features for managing subscribers), it somewhat clashes with the existing Visibility field for posts (which WordPress has had for nearly ever). It would be nice if this feature integrated as additional Visibility options (where it really belongs). Additionally, it would be good if, as with the visibility modes (private/password protected), there was an indication in the front-end that the post is not accessible to everyone while logged in (to help avoid surprises).

Intel Arc A380 as a Plex Media Server Transcoding Accelerator on Linux

Previously, if one wanted hardware accelerated transcoding in one’s Plex Media Server, the options were to either use a Nvidia card, or use an Intel CPU with QuickSync (and a platform that enables the iGPU). With Intel releasing the Arc series of GPUs, a 3rd option emerged. Recently, low profile variants of both the Arc A380 and Arc A310 have become widely available, presenting a low cost, low power, and easy to fit hardware transcoding option. On the software side, not much is needed to get hardware accelerated transcoding working with the Arc A380/A310.


First up, you will need the Intel graphics drivers in your kernel. Check your distro’s guides for how to do this (Gentoo has a fairly good wiki entry on this). One item to note, the choice of whether to compile the driver as a module or include it in the kernel depends on your setup. A general rule of thumb that has worked for me: if you use an initramfs, compile the DRM_I915 driver as a module; if you use efistub as your bootloader, build the driver into your kernel and include the firmware into the kernel image.

If you need to include the firmware into the kernel image (building the DRM_I915 driver into the kernel instead of as a module), you will need to install the linux-firmware package before compiling your kernel. Under the firmware loader settings, you’ll need to include the following firmware blobs: the dg2_dmc, dg2_guc, and dg2_huc. As of Linux 6.4.13 these are the versions the i915 driver will want: i915/dg2_dmc_ver2_08.bin i915/dg2_guc_70.bin i915/dg2_huc_gsc.bin


After rebooting with the new kernel, within the Plex Settings, under the Transcoding section, enabling hardware acceleration should be available. Additionally, the Arc A380/A310 should show up in the Hardware transcoding device dropdown. Make sure both “Use hardware acceleration when available” and “Use hardware-accelerated video encoding” are checked. For the “Hardware transcoding device” option, if you have other GPUs, you may want to select the Arc device so it is targeted. Don’t forget to press the “Save Changes” button.

While Plex is now finding the device, it still may not be able to use it just yet. If libva isn’t installed, Plex will not be able to use the Arc GPU for transcoding. For funtoo users, ensure that your profile has the gfxcard-intel mix-in and then install libva. At this point, hardware transcoding should work. You can double check this by using intel_gpu_top while playing a video. Another method of checking if hardware transcoding is working is through the “Now Playing” section of the Plex dashboard. If you see a (hw) next to the codec and the word Transcode in the video section, hardware transcoding is working.

Note that getting hardware transcoding working with Plex Media Server only required the Intel graphics Linux kernel driver, some firmware blobs, and libva. X server, Wayland, a window manager, and desktop environment were not needed or installed.

Fixing the ‘btrfs block device size is smaller than total_bytes in device item’ Error

Recently, I ran into a problem with an old SSD formatted with btrfs. The filesystem refused to mount. Checking dmesg I had an error stating that "the device total_bytes should be at most NUMBER1 but found NUBMER2", where NUMBER1 is less than NUMBER2.

The solution is to use the relatively new fix-device-size feature in btrfs rescue. This was added sometime after 2022, likely in Linux 6.3 (the patch to add this feature was submitted in the kernel developer mailing list in mid-2022). At the moment, I can confirm that 6.4.13 has this feature. Syntax wise, the command is:

btrfs rescue fix-device-size <device>

Just replace <device> with the /dev/ path to the device you are having issues mounting due to the size missmatch. This should work for most cases where the total_bytes for the device is only ‘slightly’ larger than the actual device size.

Breadcrumb NavXT Menu Magic 2.3.1

Announcing an update to Breadcrumb NavXT Menu Magic that enhances PHP8 compatibility. The previous version improperly set the URL to NULL when generating an unlinked breadcrumb (a remnant of Breadcrumb NavXT behavior prior to 6.4) . This resulted in PHP warnings being thrown within the bcn_breadcrumb::set_url() method in PHP8 environments. With version 2.3.1, Breadcrumb NavXT Menu Magic now uses the proper API calls for Breadcrumb NavXT 7.0 and newer.

Users with valid and activated license keys should receive an update notification within the WordPress dashboard and be able to use the update mechanism to update (just like with any plugin in the repository). If you run into any issues, please open a support ticket.

Breadcrumb NavXT WPML Extensions 1.5.6

Announcing an update to Breadcrumb NavXT WPML Extensions that enhances compatibility with the WPML 4.x. Previously, WPML transparently handled translation of Custom Post Type (CPT) labels, including when displayed in the breadcrumb trail. However, at some point this behavior stopped working. Breadcrumb NavXT WPML Extensions 1.5.6 adds a new translation domain, “Breadcrumb NavXT CPT Title”, which is populated with the CPT titles for translation. These titles are registered every time the Breadcrumb NavXT settings are saved in the settings page.
