I've seen that others have had this error:
After turning on the plug-in, I consistently get:

"Error 500 - Internal server error

An internal server error has occured!
Please try again later."

...but I have not seen a reply as to how to fix it. My installation is extremely vanilla - same domain for vB and WP with no custom modifications to either. vB is installed in /forum and WP at the root. No database prefix. I've applied the 755 chmod to each of the WP folders.

The only thing that I can think of that is not out-of-the-box is that I have PhotoPost installed and integrated with vB and that is all working just fine. Is there a chance that a permissions change there is keeping this bridge from working?

Any help would be appreciated as I'd like to get this going before the site goes live. I have temporarily removed this mod since it wasn't working.

Thanks,
Lloyd

You are having a conflict with other plugins. disable everything else and install this. then enable one by one..and see which one is causing it.

if you turn off the forum the themes of wordpress will crash.. any idea how to fix it?

Only thing I can think of is turn off the wordpress too :)

I think a great solution to the userid issue would be to just have every post from wordpress come into vbulletin with a generic userid, like 'Front Page' or something like that - which is possible, but not if you're signed into the forum, even if you have the autointegration turned off.

It also doesn't work in scheduled posts, annoyingly.

I decided to start over from scratch because I could not get by the Error 500 message.
So I created new databases and installed just the newest versions of WordPress and vBulletin. No mods or plugins have been added. I created a single user in vBulletin named Integration - ID is 2.
I've created no new categories and so am just using the default category which is ID 2.
The forum url is http://nameofmysite.com/forum
The relative path is /forum
I've turned on the plugin
The site uses UTF-8
Auto-Integrate is NOT turned on.
Post articles to forum is turned on.
Excert from post is turned off.

When I try to write the test post, I see the drop-down box with the correct 'Main Forum' category and when I click Publish I get Error 500.

Does anyone have a suggestion or would someone be willing to login to my site at 1and1 and look at my setup? I can PM you the login info.

Just a continuation of my last post...

I am still getting Error 500, but I now see that my posts are showing up in the forum. So I guess my new questions is - should I be concerned about the Error 500?

Also, should I assume this has been a successful test and turn on Auto Integration?

I have an exactly same problem.

That is the only one big issue I currently have with this great mod.

Since today my website isn't reachable anymore, returning the following error:
I had to delete the vbbridge-files manually to restore the functionality, though I can't use the integration now. Reuploading the plugin doesn't help and even the resetvbbridge.php-file returns that error.

Is there any way to get vbbridge working again?

/edit:
Okay, re-installing the plugin does actually fix the problem.
But it seems that it's only a matter of time until the error comes up again - and I have absolutely no idea what causes it. I've seen that there are some other users with the same problem, so maybe it's a bug in the script?

I am sure most of you who are having the problems are not following the instructions correctly. You will not get any error if its followed step by step. I have tried it myself and I finally got it what was causing those issues.

Anyone wanting to setup the bridge and make it work once and for all can PM me. I'll be happy to set it up for you making it worth my time. :)

also about the USER ID issue, as far as i know this mod is not designed for that. I hope the author will fix that in the next version so for now, there's no use talking about it, simply don't use the posting feature at all for now. If you want only users integrated that will work perfectly. (and that's what most of the people actually want!)
