Thank you, @phbyerly.

I installed the plugin on a test site and was able to recreate the issue.

Adding these lines to the functions.php of the active theme resolved the issue after I reactivated the Lock and Protect System Folders option, and the plugin is now loading correctly:

<?php
add_filter( 'sgs_whitelist_wp_content' , 'whitelist_file_in_wp_content' );
function whitelist_file_in_wp_content( $whitelist ) {
   // $whitelist[] = 'plugins/ozh-admin-drop-down-menu/wp_ozh_adminmenu.php';
	//    $whitelist[] = 'plugins/ozh-admin-drop-down-menu/inc/adminmenu.css.php';
		    $whitelist[] = 'wp_ozh_adminmenu.php';
	    $whitelist[] = 'adminmenu.css.php';

    return $whitelist;
}

Hello @generosus,

We are aware of this limit, and as a workaround, we suggest using the PageInsight URL tester directly. The results you will get are the same as the tester in our plugin is PageInsight.

We use an API call to PageInsight to get the results directly in the plugin’s interface. However, there are certain limits imposed by Google on API usage that can’t be increased.

Hello @ov3rfly,

We marked the thread as resolved as we already passed the information to our developers, who are evaluating the request. Unfortunately, we can’t provide you with any ETA for deploying such a fix and if it will be in any recent releases.

We will keep this thread as ‘not resolved’ as you requested until such a fix is deployed in one of our future updates.

Hello @generosus,

Our developers looked into the request. Due to its current adoption rate, we won’t be adding the AVIF format to SG-Optimiser for now.

We will continue to monitor it and consider adding it once its adoption increases.

Hello @viperboys,

I checked the site, and it is not showing error 500 at the moment. I checked it several times, and it loaded correctly every time.

To check this further, we will need to recreate it and test the site and see what might be causing this, as error 500 is a general one, and one of the probable causes is a plugin conflict or not emptied cache from another plugin.

We can’t do this through the forum, though. Any action on the site is against the forum rules, thus, please submit a ticket to us through our ticketing system, and we will assist you.

Hello @delanthear,

We checked the case with our developers and a, and a permanent fix for such issues fix for that, on our end will be deployed with the next release, which is expected next week.

Until then, you will have to use the workaround described in the initial post you attached.

Hello @joyarzabal,

You can try turning on the Broweser-specific caching option, as it resolves most such issues when there is a difference in how the site works on mobile and desktops.

The option is located on the admin page and its path is:

Admin >> SG-Optimizer >> Caching >> Turn on Browser-specific Caching

If the problem persists after turning this option on and clearing the website’s cache, it will be better to submit a ticket to us on Siteground through your User Area.

Finding what is causing this will likely require a more extensive check, and we will need access to the specific site and its setup to check it further. As such, access is against the forum guidelines and rules, and we won’t be able to assist you with that here.

Thank you @hecttech08,

I forwarded the information from your developer to our devs, and once we receive an update from them, we will update the thread.
