[siriuxs]

Hi, yesterday I have migrated on VPS, and now when I run the generator sitemap it response with an error:

Fatal error: Allowed memory size of 20971520 bytes exhausted (tried to allocate 4096 bytes) in /home/admin/domains/pchs.it/public_html/generator/pages/class.http.inc.php(2) : eval()'d code on line 77

Why

Hello,

you should increase memory_limit setting in php configuration (php.ini).

How much memory I must allot? I have incresed it from 20mb to 30mb, but not enough...
