403 error

[Diego Andrés]

I'm getting a 403 error when viewing items.
Could this be a random issue? Just happened today.

I know I could change the ;id=ID to &id=ID but I'm just wondering if there's something I might have touched in the source file by accident that could have caused it, or maybe some other file on my forum root.

Could also wait until tomorrow to see if it gets fixed by itself, I don't know.
Also, any other solutions? In case I can't sort it out, apart from the & thingy.
