phpBB has not problem with the tex tags. I can generate any equation in the codecogs editor and copy to document and post it with no problems. But if I edit a post in phpBB and I enter spaces the the html "br/" codes appear. So ultimately everything works but it's annoying to not be able to put some space (in phpBB) after the initial cut and paste.

When you type thing in Latex spaces and new lines are ignored, so codecogs editors behaves properly. If it was programed to ignore br html tags it would be nice.

Here an example of what I'm doing; On my forum if I type;

[tex]\\x+7\\x+6[/tex] I get (this one is good)

<img src="http://latex.codecogs.com/png.latex?\x+7\x+6">

but if I type

[tex]\\x+7<br/> \\x+6[/tex]

then I get (it should be the same)

<img src="http://latex.codecogs.com/png.latex?\x+7%3Cbr%20/%3E\x+6">

I know a reply to my post now is simply to say "Well remove all spaces!". This is what I'm doing now to make it work but when you type long solution to questions (I'm a math teacher) online without the freedom of editing your code with spaces it makes it very annoying. It was actually working on my old YaBB forum perfectly... so again I think it's an issue on the phpBB side. I a find a solution I will post it here.

Thanks again for all your replies! :)
