did any body found a solution on that?
yesterday i tryed to upload 25 buttons at a side bar with 4 levels each..
at the beggining everything was going fine ..
then the more uploads i did , the most of the time it took until i got
that error.
im using twenty eleven and i tried first a simple way
i added set_time_limit(200) to wp-config.php
because the error comes basicaly from the time limit..
.it worked but when i refreshed i got an extra error probably from
a conflict with the header php..
i found this code and add it to .htaccess file
php_value max_input_time 200
php_value post_max_size 20M
php_value max_execution_time 200
php_value upload_max_filesize 15M
stiil takes time (about 1,5 min) but at least it works!!
