Hello,

I´m trying to upgrade from 1.6.3 to 1.6.4 In my MyBB Installation Wizard Upgrade Process I´m having this message:

Quote:Fatal error: Call to undefined method datacache::update_threadprefixes() in /home1/vtfoneco/public_html/bb/install/upgrade.php on line 598

I´m still with 1.6.3 Confused

Thanks.

PD: All files were replaced since I didn´t find any "Changed Files" available to download.
Which package did you use? You need to make sure you get it from here:

http://www.mybb.com/downloads
I think I took it from the Blog...I´m gonna download it again and upload the whole thing again.
You mean from the last blog post? How could you have not seen the red bolded text? You shouldn't use that if you're upgrading from 1.6.3. There was no changed files package because 1.6.4 changes all files, so you should use the full package.
It was on the Blog but under the "Upgrading from 1.6.3 and Other Versions", where says "First, download MyBB 1.6.4".

I´m currently reuploading the whole thing.
Solved...upgraded Smile

Dont´ understand thou why all files must be changed, including my logo.gif
