Search
Did you search the forum for similar questions?
Yes, i did. Some of the responses pointed to increases the php.ini post_max_size and input_max_vars. Currently my max_nput_vars = 60000 and post_max_size is 500M but this does not solve the problem. There were initially permission issues that have been resolved.
Logs
Did you check the logs? Yes
Was there anything pertinent in them? Yes
