Facebook widget code messing up the page

[ComoEstaEso-com]

Hello everyone,

Everything was running fine on my forum.
I decided to add a facebook widget with the latest posts to a certain layout.
When I did this, various "code" lines appear on the top of the page... and then the page loads fine.
Below a screen shot of the facebook widget inserted into this layout, on the right.
You can see the "code" lines on top.

To fix, I have to remove the facebook widget, clear the system cache vB CP --> Maintenance --> Clear System Cache
Then reload the page.

After that is done, all is good.
Below a screenshot of the page with everything working as it should.

The odd thing is, that his happens only on a page where I'm running a javascript.
I have been running the facebook widget in question in the same forum, yet in pages with a different layout, and without the javascript.
It works fine.

I don't know if it's the javascript that's messing up the code, or what.

Here's part of the "code" that's coming up:

Warning: unserialize() [function.unserialize]: Function spl_autoload_call() hasn't defined the class it was called for in [path]/vb/cache/db.php on line 151

Any thoughts on what I can do to fix this?
What could I check to try and narrow down the error?

Thank you very much!

Questions/Problems regarding modifications/styles need to be asked in the modification/style thread. That is where the support for modification/style is - not out here in the main forums. Please note that if a modification/style is unsupported (or even if it says it is supported), you may be on your own if you chose to install it.

Hello Lynne,
Thanks for the reply!

Well, thing is, I removed all modification which I installed for this.

I still have mods running in the forums, yet since these errors started coming up, I have removed all changes/mods I did.

So right now the forum is running pre-errors.

Any thoughts on... what to check?
Thanks... I'm just stumped on this.

I clear the cache, and the error goes away.
Then during the day, it comes back.
Both to me, and visitors.
From different machines, and different ISPs.

Thanks

Have you also removed all the files from the FTP for all custom plugins as you still seem to have some customs things running

Did you make sure to actually delete the widget from the vBulletin CMS > Widgets page before you uninstalled the modification? If you didn't, then the widget may still be in the database.
