Turned on the plugins and site died

1.5.22 is absolutely fine for JFBConnect. We work with anything above 1.5.15.

If you're getting a blank white page, can you please turn on error reporting, enable the plugins, and let us know what the error you're seeing is? To enable error reporting, you can see the guide on the following page:
www.sourcecoast.com/extensions/troublesh...ng-joomla-extensions

As for possible causes, it could be a few things. The main time this generally happens is if you've installed all the profile plugins and enabled them, even for components that you don't have installed. Just a thought, but if you can post the error, that will really narrow it down.

Thanks!

Patlee,
The function hash_hmac is a standard PHP function, that's been available since PHP 5.1.2 (see: php.net/manual/en/function.hash-hmac.php)

There's no reason that I can think of that this should be throwing an error if you're on PHP 5.2.17. I'll do a little investigation to see what we can do, but can you verify your PHP version, and if you wouldn't mind, let us know what hosting company you're on so that we can see if there are any known PHP problems with that host.

Thanks,
Alex

Pat,
Very sorry for the delayed response. We were at Joomla Day Austin yesterday, and responded to most posts, but noticed that this one got missed.

We'd love to get into your system to understand why that function seems to be missing. If you would, create a super admin account for your site, and Private Message us the details. You can PM me by clicking the arrow under my picture (<

Thanks,

Pat,
I did a bit of digging, and looking through your site configuration. I believe you'll need to contact your hosting provider. Basically, the hash function that's throwing the error has been included in PHP since version 5.1.2 (a few years ago). If you go to Help -> System Info in Joomla, and click on "PHP Information", you can search for "hash". When you do, you'll see:

mhash
MHASH support Enabled
MHASH API Version 20060101

On our server, we have:

hash
hash support enabled
Hashing Engines md2 md4 md5 sha1 sha256 sha384 sha512 ripemd128 ripemd160 ripemd256 ripemd320 whirlpool tiger128, 3 tiger160, 3 tiger192, 3 tiger128, 4 tiger160, 4 tiger192, 4 snefru gost adler32 crc32 crc32b haval128, 3 haval160, 3 haval192, 3 haval224, 3 haval256, 3 haval128, 4 haval160, 4 haval192, 4 haval224, 4 haval256, 4 haval128, 5 haval160, 5 haval192, 5 haval224, 5 haval256, 5

So it seems like the PHP running on your server was built to include the 'old' hashing functions before they were included in PHP. In PHP 5.3, the old functions aren't even supported anymore, but it looks like they can still work in PHP 5.2.

With all that said, I'd contact your provider and see if they can enable the "hash" functions that should be built into PHP.

Hope this isn't too confusing. You don't need to know what hashing functions or other stuff is, just that you need it, and Facebook, unfortunately, requires it.

Thanks,
Alex

Pat,
Fantastic! Just so I have a better understanding, did you disable the MHash library and enable the standard Hash, or something else? Would be good to know in case others run into this, but don't have a setup with that configuration to really test with.

Thanks for the feedback, and glad we got you going,
Alex
