The W3 Total Cache Image conversion service stopped working a few weeks ago on my WordPress/WooCommerce app. It worked out well earlier. I am using PHP 8.2 and Memcached, and W3 Total Cache version 2.4.1.
In the media library, it says it is still processing images. It has been stuck for weeks.
I can see quite a few error messages in the Apache log file:
Got error ‘PHP message: PHP Warning: Incorrect cache engine in /path/to/my/webapp/wp-content/plugins/w3-total-cache/Cache.php on line 74’, referer: https://…/wp-admin/upload.php
Has anyone come across this error message?
Is there a way to get this fixed without losing any WEBP images that have already been converted from PNG to WEBP format? I’ve hundreds, if not thousands, images that have already been converted and attached to products. I would not like to have to attach the pictures one by one again.
