Error

[Steve_Stifler]

Where do I find out what errors mean? I keep getting this error when I try to have a page use HTML: (IT is in White, for some reason I can't change the text colour)

Fatal Error: Uncaught Error: Call to a member function and() on null in /home2/investo5/public_html/site/templates/_main.php:49

That error is a generic PHP error message, so making sense of it requires some basic PHP debugging skills. There's no manual here – just read the message, see what it is related to, and try to figure it out from there. Google is your best friend when debugging PHP code ?

The message here is rather clear:

Fatal Error: Uncaught Error: Call to a member function and() on null in /home2/investo5/public_html/site/templates/_main.php:49

In other words you're trying to call function and() on a null value in your _main.php file, line 49.

The exact reason is impossible to say without seeing the code, but my guess so far would be that you're grabbing a page or something like that, and not actually checking that it has a valid value before trying to use it as an object.

if it's this line from the "regular" site profile, maybe you don't have any pages other than home?

If this is the line with the error, then $home would be null.
