Thanks Sama55,
As mentioned in previous question, when I click on the Answer button, I get the duplicate_content error. but the answer is saved
We have tried Sama55's solution with deactivating all plugins and did (grep) search with "filter_answer", but it didn't work.
We don't know if this is something related to plugin or server config? is there any solution to figure out if there is something related to server or Q2A plugins ? and how to fix it
