@ican6380 Could you please ask your host to increase max_execution_time value in php.ini file and then try to re compress the images and check if it works?

@dareko Could you please try to delete/uninstall the plugin and install it again and then activate it and check if it works?

@mgboerni Have you performed a conflict test yet?

Try deactivating all plugins except for WP-Optimizeand see if it is resolved.

If so, reactivate each plugin one at a timeuntil you find the culprit. You can check for the issue between activating each plugin, so you can see which one is causing problems.

Please let us know your findings.

@wp2019s You’ll have to use the filter outside the hook function call.

add_filter( 'wpo_purge_all_cache_on_update', '__return_true' );

So it will purge all the cache whenever you update the post/page or create a new post/page.

@digrand It’s not possible to exclude the CSS class at the moment, you’ll have to check with the plugin author if there are any specific files generated for the AJAX cart and then you can exclude the path from WP-Optimize > Cache > Advanced settings > URLs to exclude from caching.

@ldeschenes Please click on show advanced option and then click “Mark all images as uncompressed” button.

Once the images are uncompressed you can compress the images to maximum compression.

@tg64 I’ll have to check this with our development team and update you soon.

Thank you for your time and patience.
