It happens when i loggin the user and i go to main page. I'm Brazilian, and my main page is in pt-br, I dont know if this is the problem.

Ok, I solved the error above, this error is caused by the SpecialUserPageViewTracker.php(29) where you miss 2 square brackets around the 29 line.
When I changed it the error is gone, but the timestamp continue borked with the question marks (like in the screenshot).

So, for now, I changed the UserPageViewTracker.sql to generate the user_page_view(1) table with the "last" column in TIMESTAMP, it will update the time everytime something get updated in the same line.

I delete the "concat" from the UserPageViewTracker.php(51) too.

I need a fixed update to use the extension correctly, this generated timestamp is three hours foward from me, i tried to solve it, but the database doesn't follow the SET time-zone command.

Another update, I solved it, it was not a problem with MySQL, but the code started to work and was overwritten the "last" column on MySQL.
SO, I think I've found the source problem: the table need to have at least a value in the "last" column to start generating a correct value, so, if you have another account, it you bug again.
For this I continue with the temporary solution, changing the SpecialUserPageViewTracker.php(28-30) to not have the $last overwritten.

@Andrewmvk Hi! Thanks for all the debugging, but I honestly cannot reproduce your issue or understand what was your final fix. If you could just write one more time to clarify, I'll be happy to incorporate your changes to the extension. Cheers!

Ok, sorry for the delay in answer.
Ignore the last update I did, the first problem was fixed (icrement bug), the second (last showing "?????????" rather than the actual date) was a problem with MediaWiki's database generation.
Like I said before, i'm brazilian, my wiki is in Pt-BR, we have accent in the words, so we use UTF-8 unicode-ci, but MySQL was configured to generate databases with UTF-8mb4 and this caused the second error.
