Finally got a chance to try upgrading the 1.6.9 install to 2.4. I started over as you suggested but after the process reached the 2.4 version change in the process, it threw up the below error.
A Database Error Occurred
Error Number: 1054
Unknown column ‘wm_x_offset’ in ‘exp_file_watermarks’
ALTER TABLE `exp_file_watermarks` CHANGE `wm_x_offset` `wm_hor_offset` int
Filename: updates/ud_240.php
Line Number: 83
In searching through the ud_install files, ud_240 is causing the error. I checked the DB watermark file and saw that the changes indicated by this file had indeed been made. The also ran its coarse and created the remaining DB files called for in the ud_240.php
Also, when the upgrade process hit this file the browser screen went blank and the install halted.
Out of curiosity I proceeded as though the install completed and opened the CP where on the home screen the following Notice appeared—-
“Your ExpressionEngine installation’s version (2.3.1) is not consistent with the reported version (2.4.0). Please update your installation of ExpressionEngine again.”
I Noticed other are now having the same problem! WHAT’S UP WITH THIS!!!!
