As you can see, the last module loaded there is "mod_security2", add the code below to a .htaccess file and save it to your public_html folder.

<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off
</IfModule>

After, try to edit and re-save the templates or all the vb settings at once.

done
same problem persist
I added

<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off
</IfModule>

to top of my htaccess in the public html

Unfortunately that doesn't always work, ask your host to disable mod_security for your site.

Also, make sure you clear your cookie and cache/temp internet folder and restart it and test it again.
