Adding the iframe tag to allowed html is not recommended as it opens you up to hacks. The script already has a setting to allow youtube iframes and it's put through the parser I think. Not sure how it's made safer but I would not recommend adding iframes to allowed html.
I will note, to any others out there with SSL, that a while ago, I did add a "s" to http for vid.ly instances I stumbled across when looking for youtube instances, so I don't know if my changes made a difference.
The knowledgebase has the tutorials for managing phrases which is where you change site phrases, installing or making language packs, making add ons, etc. It just depends on exactly what you want but please check the knowledgebase and my site. You will want to see the plugin tutorials in the knowledgebase if you need plugins and the making a theme tutorial for that also.
Please submit a ticket to support so our technicians can come check it on your site and database in case it is a bug or a site issue. I am not 100% sure what the issue is you are posting though.
Thanks Sith that's handy to know as i didn't realize they could do that, Spammers and hackers / Virus makers are my pet hate, as i can't understand what pleasure they can get from ruining someone elses hard work that can take them months and months to build and design etc
It voids all support by editing that file. I suggest to ask in a ticket to support about the issues you had before you edited the default files, noting that you will need to revert your edits in order to have support.
Ok got it working. Set the Guest user group for the User settings to be able to upload larger size profile photos. It does not work just to set Registered as my tests showed it won't work, as your site showed it not working. However, when I changed the Guest user group permissions for User >> Max file size for profile photos uploaded in kilobits , it then worked.
Thank you data. That solved the problem for me too. cheers
