What's going on here, is that there is a default htaccess rule trying to say that there IS a file to be served which you request that URL, but that it is NOT a file that apache is WILLING to send you. Usually, this only occurs if your browser demands a certain type of response, which the host cannot provide (like HTTPS if you don't have a Cert installed)
I'd also suggest taking a closer look at these PHP errors:
- Possible break in URL handling:
- Notice: Undefined offset: 1, Line 54 of [html_directory]/e107_handlers/bbcode_handler.php(388) : eval()'d code
- Long line of failed constant definitions, which can have unknown implications:
- Notice: Constant USERIP already defined, Line 1649 of [html_directory]/class2.php
- Notice: Trying to get property of non-object, Line 716 of [html_directory]/page.php
There are a laundry list of PHP Notices. Some PHP Notices are no big deal, but most of these are not "no big deal."
- Undefined index or offset, means something tried to access a member of an object or array, that didn't exists. Normally, that means there's a mod, library, or version mismatch somewhere.
- Undefined variables, Use of undefined constant, Constant already defined; these errors mean that there are whole variables and objects which should exist but don't, and others that are trying to be created but can't.
- I would be shocked if this code would ever worked.
- I would be appalled if developers just launched with all of these notices in production code.
