2.0.22a to 2.6.10 Upgrade gives blank page

[coxi]

On an other topic, I said I had the same problem.
Effectively, if you turn on VMdebug, then your frontpage come back... Turn it off, it doesn't matter, le site is still alive !
I tried before to clean the cach, but without any effect.

Notice that if you use VP Onepage checkout, like me, this great plugin replacing your cart don't work as it... You must also upgrade your plugin ($50+).

Last but not least, Paybox payent method cause some problems. I have old plugin which is working fine. The new one don't send mail to validate hmac secret key.

regards.

Hello

The new one don't send mail to validate hmac secret key.

You have to request the HMAC key in the Paybox Back offcie. It is Paybox that will send you a link in an email to validate the key.

Hello

I've got reporting to maximum
I have nothing in the log directory, so nothing is showing up
SEF is turned off

Blank screen means a fatal error.
Please turn the debug in VM also to 'administrator'.
If you can log in on the front end, do it.

and then the reason why you have a blank screen should be displayed.

You can also disable in the joomla plugin manager all payment plugins that you do not use.
