 * All 40 of my plugins deactivated themselves today, I get an error after each 
   one saying “Plugin does not have a valid header.” This just started today and
   I never had a problem like this before. I am running on Hosted WordPress through
   godaddy and tried restoring back to 2 days ago when I know for sure the problem
   didn’t exist. I got the plugins working but about 10 minutes later they all deactivated
   again. The first thing I did today was click on the plugins tab because it had
   the little 2 notification on it showing that there was 2 plugins that needed 
   updated. As soon as I clicked on the tab it showed me all the plugins were deactivated.
   I sell thousands of dollars worth of subscription ads a week and I can’t have
   problems like this. Please someone help!

 * – try deactivating ALL (yes all) plugins temporarily to see if this resolves 
   the problem (plugin functions can interfere). If this works, re-activate them
   individually (one-by-one) to find the problematic plugin(s).
    – if you can’t 
   get into your admin dashboard, try [resetting the plugins folder](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)
   by [FTP](http://codex.wordpress.org/FTP_Clients). Also remember to deactivate
   any plugins in the mu-plugins folder (if you have created such folder). The easiest
   way is to rename that folder to mu-plugins-old.

 * Thanks for the input. I believe this is a server problem as now I am unable to
   access my server at all, not from wordpress dashboard or ftp. GoDaddy sure knows
   how to drive customers out. Think I may be making the switch over to hostgator
   in the near future.
