Hello,
I got "API Error Code: 100" error so I upgraded to the new version (JFBConnect 3.0.2).
Now I tried to log in with facebook and I got an error "An error occurred with homehotel application" and then when I closed the window joomla logged me in with a user that is not me (some user I don't even know.)

This is my website :
new.homehotel.co.il/

I need to fix this ASAP, please help.

Thanks,
Shani

We just tried to log into your site without issue. We had to create a new user, as the account we had before had been disabled (which is good, since I think it had admin rights).

When you logged in previously, did you possibly have a different Facebook account open in another tab? When the login occurred with an unknown Joomla account, can you look up that account and verify when it was originally registered, what the last login date was, and (probably most importantly) what the user ID was? Finally, in the JFBConnect usermap area (in the admin section), you should be able to see who's Facebook account that Joomla ID is connected too... simply clicking on their Facebook ID should take you to their profile page. JFBConnect has a ton of checks to ensure that the correct user is logged in. If you think the login was incorrect, we definitely want to help you get to the bottom of it.

Thanks

Hello,
I understand what was the problem there. It was a problem with the db. but I have another problem :
I was working on a new version of my website in here :
homehotel3.zone1global.com/index.php

I added JFBConnect to the website and every worked fine.
Yesterday I've wanted to move my site to the production server and when I changed the URL in the facebook application for JFBConnect I started to get "API Error Code: 100". I came here and read I need to upgrade JFBConnect to the latest version.
I did the upgrade and since I keep having errors in my website.
errors like :
"Warning: include() [function.include]: Filename cannot be empty in /home/gahlnir/public_html/homehotel3/libraries/loader.php on line 140

Warning: include() [function.include]: Filename cannot be empty in /home/gahlnir/public_html/homehotel3/libraries/loader.php on line 140

Warning: include() [function.include]: Failed opening '' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/gahlnir/public_html/homehotel3/libraries/loader.php on line 140

Fatal error: Class 'JModuleHelper' not found in /home/gahlnir/public_html/homehotel3/libraries/joomla/document/html/html.php on line 272"

"Allowed memory size of 67108864 bytes exhausted (tried to allocate 62652409 bytes) in /home/.../public_html/.../libraries/joomla/database/database.php on line 619"

I can have one of this errors and after a few minutes the same page works fine with out me changing anything.

You can see the version without the errors here :
homehotel3.zone1global.com/index.php (with the "API Error Code: 100" error), and the version with the upgrade here:
new.homehotel.co.il

I don't understand what's causing this errors, please help

I'm not sure. Those errors don't look to be coming from JFBConnect at all. From a quick check of what I could, JFBConnect seems to be installed properly.

The fact that "JModuleHelper", which is a vital piece of Joomla, cannot be found makes me think that the entire site was not properly backed up and loaded to the upgraded site. To verify that JFBConnect isn't the cause, can you try disabling the JFBConnect plugins and modules, and see if you still have issues?

Hopefully this helps narrow it down.
