My site was running good until recently. Suddenly none of the modules were able to use jQuery on the site. I came to know about this when I logged in as admin and my Nodequeues were not working.
The button on Panel pages on the top of each region to add content using CTools has also started behaving weirdly. Earlier one had to click on the button on top of each region to see the menu that said "Add content" but now that menu is fully expanded without clicking.
Is it correct to conclude that all this is happening because the modules are not able to access the jQuery library? The jQuery UI and jQuery modules are installed and were working properly before yesterday.
