 * I’ve encountered an issue today that I’ve never seen before. I have been trying
   to uninstall Ajax Event Calendar because it says that magic quotes is on my server…
   I have GoDaddy hosting and they say this is not the case. I tried all the fixes
   suggested in the plugin’s support forum and none of them worked so I simply decided
   to go with a different calendar, however, whenever I deactivate ANY of the plugins(
   because I saw a few junk ones in there that I don’t need) none of them are saving
   as deactivated and I get this message when I click to delete them:
 * > Warning: Cannot modify header information – headers already sent by (output
   > started at /home/content/17/9902817/html/wp-content/themes/magazino/functions.
   > php:902) in /home/content/17/9902817/html/wp-includes/pluggable.php on line
   > 1121
 * That seems to be something with my theme, right? This has never happened before,
   however, and I’m thoroughly confused and not sure what to do from here. When 
   I tried to just skip the plugins and install a new one, it showed that it was
   successful but is not showing in my list of plugins now. I’m totally at a loss.
   The website, if it’s necessary for assistance, is blisstival.com.
 * Thank you in advance for any advice. 🙂
