Problems after moving host.

I have recently moved host and had numerous problems with my Joomla site after the transfer. Most have been rectfied, but still the CAPTCHA image does not generate in ChronoComments. Most problems thus far have been solved by updating an URL somewhere, yet after uninstalling/re-installing ChronoComments and having run through the index.php and style.css files, I's still clueless as to where I need to make adjustments.

Can anyone help with this matter? It would be greatly appreciated.

Hi kevco33,

There's a FAQ on this which suggests a couple of things to try. It's probably a permissions issue with your host and the server logs are the best place to look for the solution - but do try out the tests in the FAQ first.

Thnak you for your reply Bob. Without wanting to sound to dim, I've had a bit of trouble finding the ChronoComments FAQs! I did try that first, but all I can seem to find are FAQs for ChronoForms, which I'm not using.

I don't suppose you could post a link at all? Sorry to be a bother!

Hi kevco,

You're correct - there aren't any (sorry, I need my second cup of coffee this morning). But the ChronoVerification code is identical. If you have ChronoForms installed then check the Anti_Spam tab for the dignostics (if you don't then you can check PHPInfo to see if the libraries are installed - GD, FreeType and PNG support. And you can run the same test on the ChronoVerification.php file

Thanks very much! I'll give this a whizz now and, hopefully, I won't be back any time soon!

I'm very sorry, but I can't seem to find the relevant FAQ (having gone through around 30 of them!), and though I've looked through chrono_verification.php, I'm hesitant to fiddle with it due to the rather large disclaimer at the top!

Freetype, GD and PNG are all supported, but I don't have ChronoForms installed, so have no ANTI_SPAM Tab.

Hi kevco33,

It's #30 'Imageverification doesn't work' The relevant bit reads:

If all is well there and images still do not display then you can get more 'informative' error reports if you Change the header at line 17 in chrono_verification.php from header("Content-type: image/png"); to header("Content-type: text/html");. Then point your browser directly to that file i.e. http://www.example.com/components/com_chronocontact/chrono_verification.php
It will show PHP errors on things php cannot handle. This should provide enough input to fix the problem.

I've done this, and got a 500 Internal Server error!

Sorry, to clarify, the actual CAPTCHA image itself is still a lovely little red "X", but at poinbting my browser at ...components/com_chronocomments/chrono_verification.php, I get a 500 Internal Sever Error. I'm looking into my error log to try and see why this is as we speak.

OK! Fixed the 500 Error, and it all now works! Both on site and with the browser pointed at ...components/com_chronocomments/chrono_verification.php. What's next? Can I change it back to PNG, or should I just leave it as it is?

Hi kevco33,

Ideally you'd change it back to PNG - but, check out the main browsers and make sure it works that way before you finally decide.
