I am trying to call $.ajax from a php page and when I try to run
include_once dirname(dirname(__DIR__)) . '/mainfile.php';
It returns with a 404 not found. I think I have narrowed it down to something in the include/common.php being loaded from mainfile.php but I cannot figure out what is generating the 404.
I have done the same type of call in a different module and it appears to functions properly.

Any ideas on where I can track the issue down? I have debug on but get nothing. The onlt thinf I see in FF console is this

hi
maybe you have a problem with one of the "preload" folders in one of your modules. new modules are using index.php instead of index.html and XOOPS.2.5.10 is not covering this problem.

please install XOOPS.2.5.11

if problem is still existing please let us know which modules you have installed

thank you for the reply. I did have two customer modules that I added that had index.php in the preload folder. I replaced those with index.html and the 404 went away.

Thank you VERY MUCH! I never would have caught that!
