I opened the "core/Migrations" folder and found a lot of PHP files ... I opened all those files and replaced 255 with 55 and now I get:
Internal Server Error
The server encountered an internal error and was unable to complete your request. Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report. More details can be found in the server log.
Sadly all the solutions to fix the "CSRF check failed" error is to configure the webserver for ownCloud I can't do that... Goodbye ownCloud! the older versions worked fine
@mariolatif741 Can you show us the output from when you installed ownCloud - this should tell us which key is failing still. The other option is to install on a mysql server without strit mode enabled (which is the default actually) which will not fail on this error.
