Join form not working

Not sure what the deal is. Just noticed it tonight, no signups for a while. The join button on the bottom of the form does not work. Click it and it just sits there, no errors. Any ideas? I am upgraded to B2, but pretty sure it has not worked since I upgraded 7.09 to  7.1.

Try it....

Do you have JS cache and JS Compression turned on?

If so, try shutting them off, clear the cache, leave options off and test join form.

have you applied the e-mail block modification?,

join form might stop working if not done right.

A quick test shows that something is broken

POST http://towtalk.net/join.php 500 (Internal Server Error)

 might be it. I had the mod installed on my 7.09. maybe the upgrade changed some of the mods. Will check it as soon as the world finishes ending. (lol)

in administration / builders / profile fields (join form) email field click on advanced see if it has this
return (bool) preg_match('/^([a-z0-9+_-.]+)@([a-z0-9+_-.]+)$/i', $arg0); (that's default)

That was it. I lost all the changes to the design.inc file. Once I replaced it, all worked fine. Good catch Pro, thanks ...

you're welcome, if you need the email block mod you'll need to re-apply the code again just follow the instructions i have it working on 7.1b2

all the rest of it was still there. Seems to be working fine
