Fatal error: Out of memory (allocated 54263808) (tried to allocate 40216137 bytes) in /home/cgaqwers/public_html/sitemap/pages/class.http.inc.php(2) : eval()'d code on line 128

Hello,

it looks like your server configuration doesn't allow to run the script long enough to create full sitemap. Please try to increase memory_limit and max_execution_time settings in php configuration at your host (php.ini file) or contact hosting support regarding this.

Thanks for reply, can you tell me how much increase memory_limit and max_execution_time will be good for this script?

Hello,

that depends on the size of webste, try to increase it to 256M.

[info1521]

that's already 756MB and execution time is 180sec

Hello,

please let me know your generator URL/login in private message to check this.
From your message it seems that limit is lower:
