I have uploaded the files for 4.3.0 and got the following error:
Fatal error: Call to undefined function vbet_global_bootstrap_init_start2() in /home/<folder>/public_html/testvb/forums/includes/class_bootstrap.php(103) : eval()'d code on line 5
I have an active v4.2.3 running before I upload the latest files. I didn't manage to find any upgrade instructions. I assume that I can just upload it and overwrite the files of the previous version?
