Unable to See Right click Context Menu, Unclickable Magnifier glass, List lock/unlock is not working

[AbhishekGardade]

Few of the table forms are behaving weirdly on my PDI. Whenever I am clicking on  Magnifier icon, nothing happens, no popup appears. Even List lock/unlock is not working.

Surprisingly Right Click context menus is not available for few forms. 

What may be the possible reason for such weird behavior? What needs to be checked here?

Did you found any Root cause or solution?

seems like some client side code is blocking here. do one thing 

go to your ui policy and client script and deactivate the one which has been updated or created recently. and try again.

I tried deactivating UI Policies and client script on tables but it still not giving me the expected results.

Thank You.

have you recently added some DOM manipulation on UI Action client side code ? or any client side script ? if yes deactivate that as well. give a try. 

[AbhishekGardade]

I am using some DOM manipulation scripts and I have deactivated that firstly when I am getting these issues.

Is it related to ServiceNow upgrade activities that was done on my instance recently?
