Summary/Details/Readability tabs are always empty

Hey @amykristin75,

Thanks for trying the plugin and sorry that you are running into issues.

I took a quick look at your site and I can see that there are quite a few console errors being thrown from the pages, some related to our plugin and some unrelated. It seems like the cache plugin you are using on the site does not work well with our plugin.

Can you let me know what cache plugin you have enabled? I will look and see if there are specific settings that are needed to ensure that the cache does not interfere with how the plugin works.

I don’t believe?I have a plugin specifically for clearing cache. I am building this site as a volunteer for a local rescue and I am not technical. I’m not sure if it matters, but I’m also having an issue with Yost SEO Premium. Here is what I have:

Accessibility Checker
Akismet Anti-Spam
CoBlocks
CookieYES
Counters Block
Essential Blocks
EventON Lite
GA Google Analytics
Gutenberg
Jetpack
Layout Grid
Max Mega Menu
My Sticky Bar
Otter
Page Optimize
Poptin
Yoast SEO
Yoast Premium

Thank you so much for your help!

Hey,

The Page Optimize plugin is the one that is causing the conflicts here. It is doing some thing to optimize performance but that can sometimes cause things to break due to it making certain expectations that are not always true. It is most likely the reason accessibility-checker is not working on your site and also probably why Yoast SEO isn’t working either.

Temporarily could you disable that plugin and see if your issue with both plugins goes away?

I can find the right scripts to exclude from that plugin to make accessibility-checker work for you if disabling it fixes the problem on your site.

I disabled Page Optimize and that actually made it worse. When a page loads, there is now a flicker at the top of the page that briefly shows the page without the styles applied. The accessibility check and Yoast SEO Premium aren’t working either.

Do you have access to a staging/development version of this site where changes can safely be made to test things and to figure this out?

I have tested accessibility-checker on a local site with the page optimize plugin and it definetly does create some issues. Maybe those issues are not what is causing the panel to fail in the editor page or that blocks yoast from working – but it is causing some issue. You should add this list of JS scripts that are not concatenated to solve that:
edac,edac-editor-app,edac-frontend-fixes,edac-frontend-highlighter-app

You can find that input box by hovering the menu at Settings -> Performance and then the page that loads should have a box lablelled with Comma separated list of strings to exclude from JS concatenating:

I don’t see anything else in your list of plugins that may be causing a conflict. Do you happen to know if there is any error logging enabled on the site which you could share. I know you mentioned you were not technical so I understand if this isn’t something you know how to check.

When I go to the site settings (Settings>performance) there is not a box with that label. There is a Jetpack Search section, CDN section, Performance and Speed section, and a Media section. There is an ‘optimize JS and CSS for faster page load and render in the browser’ link, but I get a ‘sorry you are not allowed to access this page’ screen.

If I go to Jetpack>Boost, there is a Concatenate CSS section with an ‘exclude CSS strings’ link and also a Concatenate JD section with ‘exclude JS Strings’ link.

If I go to Site-logs/tenthlifecats.org/php there are PHP warnings for ‘Undefined variable $ in /srv/htdocs/wp-content/plugins/eventon-lite/includes/eventon-core-functions.php on line 745’
