JFBConnect breaks the site completely

First, sorry for the delayed response. We were returning from the Joomla World Conference yesterday, and support took a hit during our travels. Now, for your problem...

From what it sounds like, my guess as to your configuration is:
* You have the Social Profiles - JomSocial plugin enable
* You have the "Registration Component" set to "JomSocial" in the JFBConnect -> Configuration area
The white page *is* likely a PHP Error. You should be able to go to the Joomla Global Configuration area and set Error Reporting to "Maximum" to see what that error is, which would greatly help us.

The problem is likely from our new mode where a user can login with a social network but use the JomSocial registration flow. That feature was just added in v5.2. We tested extensively, but it's possible we missed something.

For now, you can likely:
* Disable the Social Profiles - JomSocial plugin (instead of the whole JFBCSystem plugin) to fix the error. That will allow more features to continue to work.
* Try changing the Registration component to JFBConnect and testing that way instead.

Once we get the error, that will help us narrow things down. If you can't see it still, let us know what version of JomSocial you're using, and we can test further from there.

Thanks,
Alex

Fatal error: Allowed memory size of 25165824 bytes exhausted (tried to allocate 122880 bytes) in

Yeessh. That error is simply stating that your site is using too much memory to generate the page. However, 250MB to generate a page is a *huge* amount, so something seems like it's going wrong on your site. On this site, for instance, we have our memory limit set to 60MB, and that's more than enough.

So, there could be problems in either area below:
* JFBConnect could be allocating too much memory and making your site go a little crazy. This is always possible, but unlikely. We do a lot of profiling and haven't heard issues like you mention from other users. Most sites/hosts have much lower memory limits as well.
* Your site was already using a ton of memory, and JFBConnect is just 'tipping' the scales over the limit.

The first is something we can obviously help to fix. The 2nd is something that we'd simply recommend disabling system plugins, removing components, and paring back anything 'extra' you have installed that isn't required.

As for:

All the settings you suggested were already the way they should be.

I really didn't give recommendations on settings above. There's lots of ways to configure things. Can you tell me if disabling the Social Profiles - JomSocial plugin fixes the issue? That will definitely help narrow things down.

Another thing to do is enable the System - Debug plugin (if not already) and then set the "Debug System" to Yes in the Joomla Global Configuration area. Then, in the bottom of each page, there should be a report of memory usage. For the pages that work, see if the number is anywhere near 250MB. If so, the 2nd point above about your site using a lot of memory applies. If it's really low on most/all pages, then it could be something strange when using JFBConnect in JomSocial.

I hope that helps get you started,
Alex

Joe,
Thanks for pointing out my error. 25MB is much more reasonable for page memory. JFBConnect still shouldn't be choking on that much, but again, it could just be "the straw that broke the camel's back".

Can you help my by doing the following:
* Let me know exactly when this happens? Above, you said it only happened after you tried to register and, then, only inside JomSocial. Is that still correct? Is there other times you see this error, or other ways to recreate it?
* Is it possible to give me super admin credentials to the site to investigate further? With the above question on how to recreate things, we'll be able to (hopefully) narrow things down.

To send me your credentials privately, please hit the mail icon under my name. That will let you send a Private Message.

Thanks,
Alex
