Installing Tubepress pro and it displayed this error "The plugin generated 240 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin."
I read thru the forum by uninstalling and reinstalling Tubepress pro, but still getting the same error.
Tubepress pro version tubepress_pro_3_1_4
Should I be concern and deactivating Tubepress Pro?
