Went to log into a local dev site tonight and suddenly get this error:

An Error was encountered
Unable to load the requested class: jquery

I have no idea what might have changed. I've replaced all of the files in the system folder, and have slowly gone back through the themes folder, replacing everything I could think of, and making sure that all of the add-ons were updated.

Currently running EE 2.6.1 with the master config in place. I enabled debug = 1 in the admin.php file but it doesn't show anything else. The front end of the site comes up as expected.

Anyone happen to see this before?

Looks like it might be an issue with the native jQuery module. Those files are in /system/expressionengine/modules/. Replace those to be sure something didn't get accidently deleted.

  • I wasn't sure exactly where those files were, but I replaced everything in the system folder (and copied back my config and database files). I replaced the entire /themes folder, copying back my third party themes and CP themes. So I figured it could only be my 3rd party add-ons (which is why I was going back through and making sure they were all there) or something with the DB. Strange.

  • After spending too much time with this, I ended up rebuilding from scratch.... :( So this can be closed.
