I have an POST admin-ajax.php 500 (Internal Server Error) that is resolved when I deactivate the Product Catalogue plugin, but my site requires the plugin to be active. I’ve updated to the most recent version, even deleted the old installation and uploaded the most recent version from scratch.
I’ve tried everything, from installing WP anew and increasing the memory limit.
I am confident that this plugin is causing this issue. Is there anything I can do to absolve this issue?
