Good day, I have a problem now with mybb, earlier I added few themes on my forum, after successfully doing so I found something wrong, me and my users can no longer edit our own post and post a quick reply. And if I click on the new reply button I can successfully post a reply but the containing message is a word "undefined" and not the actual message that I attempted to post. All these errors occurs on all the themes that I recently uploaded except on the theme that we used before. Does the error that I encountered during upgrading process yesterday has something to do with this? I did not successfully upgrade my forum and I did not attempt to retry the upgrade process. Thanks
Can you provide your forum URL and a test account?
What was the error you got during the upgrade? And which version were you upgrading from?
I sent a personal message to you sir. Here is a screenshot of the error, this is not the actual screenshot of my yesterday's attempt of upgrading but this is the same error that I encountered.

You missed some files. Re-upload all the files from the latest MyBB version and run the upgrade script again.
So you mean I have to download the whole package of the latest mybb 1.6.4? Am I gonna overwrite the existing files?
Hrm, obviously I have to
Yes, download all the files, upload them and make sure the existing files are being overwritten.
Hello, I have downloaded the whole package and tested it first on my localhost but I still get this error
I read other threads and I found similar query I'll try it first.
