For some periods now, I have been having problems installing this Wonderful theme from Theme Forest Called OneCommunity. Please is there anyone willing to help me?
What error message you have? try to upload the theme zip file via FTP. if the file is too large you can't upload it directly from the Wordpress dashboard, you have to use FTP or directly from your Cpanel.
Have you tried contacting the theme owners at themeforest? Otherwise, tell us what problems you are having
