There's a lot of wrong stuff here. To say the least, obsolete PHP (5.4 ceased support in 2015 - https://www.php.net/eol.php), obsolete Joomla (1.5 last release in 2012 - https://downloads.joomla.org/cms/joomla15) etc.

To fix the memory problem, you probably have to ask your host to increase the memory limit or simply change the setting either in cPanel (or similar hosting system) or in the php.ini file directly.

I don't know that I'd bother trying to fix such an old site running on out of date server software, and rather focus on getting the site upgraded to Joomla 3.9.6, given you have the ability to use PHP 7.

(1) Not sure you're putting the memory limit setting in the right file; normally you'd just set that in php.ini.
(2) Joomla 1.5 won't run on PHP 7....

Upgrade to 1.5.26 as a start.
https://downloads.joomla.org/cms/joomla ... format=zip


J1.5 is updated by unzipping the file, upload and overwrite all files.
