Within my Twitter developer account, I did not have the proper callback URL. The callback URL must be your site URL, but ended with /oauth/callback/

I figured out what went wrong, thanks again for the help though!

No worries at all! But yeah, I purchased Nexus/Commerce and the upgrade was a success! Now I'm just trying to figure out this Twitter sign in situation which I detailed here, but thank you so much again.

So I have the up to date software installed and I'm trying to set up social sign in via Twitter. I entered everything correctly in the admin panel I believe (entered the correct key and what not), but when I attempt to test to connect my Twitter and test the sign in, it says "Something went wrong. Please try again."

Thanks again for the help

So for a more full story here: my host upgraded the PHP and as a result, the very old version of IPS that I had and was fine with for the time being was no longer compatible and it messed up the forum badly. I was running on version 3 of Invision since my former forum co-owner and I upgraded years ago. As I touched on earlier, she had disappeared with all the information needed to renew the license and upgrade to 4 and beyond, so I'm now stuck in a situation where to upgrade and make things functional again, I have to buy it all myself. So yeah, overall this is an absolutely must upgrade situation. As for your second point, I'm not able to access the admin panel at the point I'm at, so I don't think I can remove it as an application. The reason we had commerce the first go around was because at that point we raised the funds for the forum, so we figured might as well get everything. But it did turn out that that wasn't needed, which is why I didn't purchase it again this time around. I've had a support ticket with IPS for days now and still no response, so unless you don't recommend I purchase Commerce/Nexus (honestly, if I'm spending money on it, I'll make sure to use it this go around since I'm not a teenager acting on impulse like I was when I started this forum lol), maybe I should go ahead with it just to finish the upgrade? Or should I really just wait for IPS no matter how long they're primed to take?

Ohhhh that makes a lot of sense. No I did not purchase Commerce again. Am I forced to do so now that I'm stuck here?

Should I do everything all over again then? Because I've been trying to locate where these Nexus files are after getting the same message twice now, but I haven't really been able to find them?

Thank you for your response! So I tried FlashFXP and then tried clearing my browser cache afterward, but I still get the following: I'm going to try your method, but what do you mean by exact the files?

Thank you! Trying this right now and I'll get back to you

Update: I figured out I'm supposed to go my site url /admin/upgrade However now that I'm there, it's telling me I'm missing a list of nexus files that I cannot locate in my download

And the following appears after I believe to have transferred the files using FileZilla and was trying to enter admin CP How bad did I mess up.... For backstory, I was forced to upgrade manually because my former forum co-owner disappeared years ago with the license, e-mails and what not, so I was forced to purchase the software all over again and I'm upgrading from really old software. I tried to google walk through and thought to find one, but I don't know what went wrong. Can someone please help me, I'm stressed out and just hoping I haven't lost all the forum posts and stuff like that.
