Widgets in Dashboard Imoveable – Won't Open

Hi All – first post and hope I do it right.

SavvySleuth.com is my blog, updated to WP 3.4.2 after this issue came up, hoping it would fix it – it didn’t.

Issue: Widgets within the WP Dashboard won’t move, nor those already within the sidebars won’t open.

I contacted my web server and we boosted the memory access – that didn’t fix the problem.

I changed themes to Twenty Ten and still had the problem. Current theme is Magazine Flow.

Tried reinstalling WP – didn’t fix it.

Deactivated all plug-ins through the dashboard with no luck. Ended up finding info on this board to make a new plugins folder within public_html , WP-content, and plugins. I made an old plugins folder and then a new one. Now the dashboard shows no installed plug-ins, but it does show 1 ‘drop-in’. When I go to open it I get this error: 403 Permission Denied : You do not have permission for this request /wp-admin/plugins.php?plugin_status=dropins.

I have deleted W3 Cache php files per another post on this forum, in an attempted fix. It gave me back posting functionality – another issue that came up, and the ability to use the Theme dashboard section – a third issue.

Despite this, I still cannot move or open widgets. I took a Firebug shot of the Widgets dashboard pastebin.com/b5VZwmsj which I hope it helpful.

I am a novice at WP and HTML, however I do see W3 in the first line and wonder if that’s still the problem.

Again, changing the theme, uninstalling plugins and increasing the memory to 80 has not solved the issue with the unresponsive dashboard widgets. All the other areas of the dashboard seem OK at present.

I also tried restoring from back-up from a time before this issue came up, and it didn’t fix it.

I’m sure it’s a matter of tweaking, but I’m not sure how to do it.

Any help would be MUCH appreciated. Thank you!
