Hey Thejan,
Sorry about the delay in getting to you! Your post was in the core forum, which does not get checked very often. To get quick responses from me and my team, please post to EE 2 Tech Support, which is where your thread is now.
I know this may not make much sense, but you need to increase the amount of memory that PHP can use and allocate.
That’s going to be in your php.ini file and if you are on a shared hosting provider you will have to have them make the change for you. Ask them to take you to the max and make sure they do not charge you more per month to do so.
If you are hosting this on a dedicated box then here are the values you will want to “tweak”.
Mem limit should be 64 or greater.
memory_limit
This sets the maximum amount of memory in bytes that a script is allowed to allocate.
Default size 5.3 in is “8M”
post_max_size (must be greater than upload_max_filesize)
Sets max size of post data allowed. This setting also affects file upload.
Default size in 5.3 is “128M”
upload_max_filesize
The maximum size of an uploaded file.
max_execution_time
This sets the maximum time in seconds a script is allowed to run before it is terminated by the parser.
Default setting in 5.3 is “30”
Please let me know if that helps!
Cheers,
