Hi @bcworkz,
Thank you for replying. I enabled debugging in my config file and I found two plugins with deprecated PHP. Deactivating these, while getting rid of those errors, did not fix my actual problem.
The debug.log only seems to have recorded the PHP errors. Here is what Google Console told me upon loading the page:
Upon loading:
(x6) XHR finished loading: POST "<URL>".
(x118) Mixed Content: The page at '<URL>' was loaded over HTTPS, but requested an insecure image '<URL>'. This content should also be served over HTTPS.
I used Console after trying to locate the file via the Regenerate Thumbnail plugin, but the output upon using this plugin is a ridiculous length so I won’t copy/paste it all here unless someone specifically asks for it.
I would presume that the error lies somewhere within “Uncaught Error: Syntax error, unrecognized expression: #/regenerate/16212” or potentially within the image files being served as HTTP rather than over HTTPS, possibly.
Upon using another popular plugin, Smush:
Output:
load-scripts.php?c=1&load[]=jquery-core,jquery-migrate,utils,jquery-ui-core,jquery-ui-widget,jquery-ui-mouse,jquery-ui-draggable,moxiejs,plupload&ver=4.9.8:4
XHR finished loading: GET "https://www.ecdllc.net/wp-admin/admin-ajax.php?action=wp_smushit_manual&is_bulk_resmush=false&attachment_id=16212&get_next=0&_nonce=".
And it told me that the file cannot be found.
And finally, upon using another compressing tool, reSmushIt:
Output:
GET https://www.example.net/wp-admin/upload.php?page=resmushit_options net::ERR_INCOMPLETE_CHUNKED_ENCODING 200 (OK)
((I cut about 50 lines of load-script.php here))
XHR failed loading: POST "https://www.example.net/wp-admin/admin-ajax.php".
POST https://www.example.net/wp-admin/admin-ajax.php net::ERR_EMPTY_RESPONSE
And finally, with a snippet of all the load-scripts.php?:

And that process continues to repeat over and over.
I am attempting to solve this as someone who is not trained in server errors – my training is mainly in front end development. However I’ve been tasked to figure this out so any further help is appreciated.
