Edit the membership capabilities of my PHP script Social Media site

My website uses WoWonder social media script ([login to view URL]) The script is set up to allow Free and 'Pro' members. I want the coding edited so that Free members have very few capabilities. Free members should only be able to: 1. Post status updates in plain text (no links, no videos, no images, no backgrounds) 2. Post comments on other user posts (still no links or images) 3. Add friends (and all related friendship capabilities) *These capability restrictions must also be in place on the related Android and iOS timeline apps. (if you don't know how to edit app files that is ok I can hire another freelancer) *Free members should not be able to log into Android or iOS Messenger app. Upon login attempt it there should be a warning pop us indicating "Use of this app is reserved for our Pro Members only. Would you like to go Pro?" with two buttons "Yes, I'm ready!" and "No, not yet" *If Free member attempts to perform and Pro Member Only capability there should be a warning pop us indicating "This functionality is reserved for our Pro Members only. Would you like to go Pro?" with two buttons "Yes, I'm ready!" and "No, not yet" Thank you
