The script may use certain IDs or classes in the DOM and if you have modified the template then the AJAX request may not work as expected. Try again using a fresh copy of BuddyPress to see if the problem continues to happen
I didn’t modified any template or file from Buddypress. I am using Divi theme and memberPress plugin for maintaining the members. Also used “MemberPress + BuddyPress Integration” plugin to integrates MemberPress with BuddyPress.
Is any one from above creating issue for tabs?
If you aren’t modifying the templates then check your theme or plugins in case they are modifying them. It is likely that something has changed and that change has introduced the issue.
How I check my theme or plugin conflict with that?
You will need to ask the author of your theme and plugins.
