Try disabling your modifications/plugins and see if you still have this problem.
Note: To temporarily disable the plugin system, edit includes/config.php and add this line right under <?php

define('DISABLE_HOOKS', true);

I add this line, but I have the same problem :(

Disable vbseo completely (through the vbseo admin panel, the products page, and the htaccess file) and see if you still have the same problem.

If so, also create a new style with no parent:

Styles & Templates > Style Manager > Add New Style
Parent Style: No Parent Style
Title: Default vBulletin
Allow User Selection: Yes
Save

Then browse the site using that totally default vbulletin style - do you still have the same problem?

a job after I got back in my admincp forum, but I still have problems
1 to 1 error message in the sign pictured
2 - I delete all hacks except vBSEO, I do not know why he is still in the forum
3 - I rename the file. Htaccess
4 - the forum does not open, I just have a simple blank page see link
www.joomla4ar.com/forum
5 - I install the update 3.8.7 to 4.1 but I still have traces in my panel pictured in yellow

Your database error is from a modification as there is no postid field in the attachment table in 4.1.4. Disable your modifications as I said in post 2.
