Hi Tareq, not sure what is happening with the search but it looks like something has a empty string and should not.

Since you have already cleared the search and rebuilt, then my guess is that some module is passing the search crawler a wrong value. Can you take a look in /portals/_default/logs and see if you get more details there?

As for the second issue, that usually happens when in a webforms module uses viewstate validation but some frontend code modifies one of those validated controls, this is a security measure. In order to isolate what is causing it, you would need to switch that page to the default theme and start removing modules one by one until it works, that last thing removed is probably the culprit.

Also, what was the upgrade history, was this 9.1.1 upgraded to 9.2.2, was it 8.0.4 directly to 9.2.2, etc.

Thank you Daniel, you pointed me to the right direction found the form plugin that was causing the issue. Fixing that fixed the search as well.

Always loved DNN. No other CMS I rather built a site with then DNN because of how easy it is to manage. Thanks again
