 * I have a Multiuse install with about 35 blogs – all are working fine
 * one though is giving me errors that started today… I cannot upload images or 
   add headers
 * when adding a header -I get the following msg:
 * Warning: imagecreatefromstring() [function.imagecreatefromstring]: Empty string
   or invalid image in /home/maindomain.com/public_html/wp-includes/media.php on
   line 254
 * I have researched all over…
 * I had my host increase the memory on php
    I have increased the memory for the
   blog with trouble I have host recompiling PHP and checking GD
 * what else could it be?

 * wandererz – Different error. Please make a new post for yourself.
 * Also if you’re NOT using MultiSite, this should go in the general troubleshooting
   section.
