Preview creation errors

[Dan Ruth]

I recently upgraded to v11.0, and also enabled `$offline_job_queue` in config.php

Suddenly, no previews are being created, no matter the resource type (.pdf, .jpg, .heic, .mov). When I attempt to recreate a preview when editing metadata, I get an unspecified error in my browser, and the Apache error log simply says: 

"WARNING: The convert command is deprecated in IMv7, use "magick" instead of "convert" or "magick convert".

I also see a bunch of Active jobs in my jobs queue that never seem to go away, nor change status to Complete. I have a cron job created to run pages/tools/offline_jobs.php and I've tried running it manually, but the jobs never seem to complete.

Here are my system details:

• Server: Apache/2.4.58 (Ubuntu)
• MySQL: 8.0.46-0ubuntu0.24.04.3
• PHP version: 8.3.6
• ImageMagick version: 7.1.1-48 (Beta)

I don't have a solution, but I believe the error message is related to how ImageMagick v7 works with RS 11.0, I had similar issues when trying another version of ImageMagick. I believe it's related to the function that tries to verify which version of ImageMagick you're using (it runs the convert -version command), but as you can tell from the log it gives you the message that the function is deprecated so the version checker fails, which in turn mess with the rest of the convert / magick procedure (aka creating thumbnails and previews etc)

If it's possible to run a ImageMagick version prior to 7 (the standard one should do fine), I'd try that first, unless there's a specific reason for you running 7.1 beta
