Character suddenly got disconnected. Now I can't log back in with it.

Hello everyone, I hope you are having a nice day!

Yesterday while questing in Wetlands with my main (lvl. 27) I got suddenly disconnected from the game. I've had some intermittent internet issues so it didn't bother me at first, but when I tried logging back in, I got immediately disconnected again. I tried creating another character, and that worked fine, I can play with those without problems.

A friendly player suggested that I try the Unstuck feature from the website. Did that, but the same thing happens, with the only difference that now I'm in Stormwind.

I don't know what else to try, has anyone ran into this problem in the past?

Thanks in advance.

follow this steps:
1) delete "cache" folder
2) disable all of your addon before to log with that character

I did try deleting the Cache folder, but not disabling the addons, since I've been using them all for a while before the issue... That last one worked!

So I guess one of those add-ons was acting up, I'll enable them one by one to find the culprit. Thanks a lot for your help!

do you use questhelper? Sometime it causes issues if you are on a quest with a "timer"

Well, I think I found it... Necrosis, a warlock addon I've been trying for a few days, especially its shard management feature. It even gave me a BSOD just now... That one's going to the trash...

oh, ye. That addon use a command to delete items and warmane have disabled that command (using it will disconnect you)

Good to know, thanks a lot for your help!
