memory size error - accounts - project

[Operator]

g'day,
i've tried to assign about 2500 accounts to one project, but got an memory error.
the error message is:
Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 989192 bytes) in /home/iscrminf/public_html/XTemplate/xtpl.php on line 167

is it possible to expand the memory size and how??
in wich file i've got to change the number?
in the xtpl.php on line 167 only stands: $this->parsed_blocks[$bname].=$copy;
thanks

You need to edt your php.ini and increase the value for memory_limit.
Restart your web server after that.

Cheers
