White page after manual upgrade to 9.1 - solved, when htaccess is disabled

Hi,

I use oC on an hosted environment at 1&1, Germany.

After manually upgrading from 9.0.3 to 9.1, at the first attempt to log-in there appeared the upgrade-process, which completed successfully, but, when redirecting me to my website, only a white page appears.

When I disable the original htaccess (which I did not alter) by renaming it in htaccess.txt, everything is fine, but with .htacess - white page.

Here is the htaccess:
`


SetEnvIfNoCase ^Authorization$ "(.+)" XAUTHORIZATION=$1
RequestHeader set XAuthorization %{XAUTHORIZATION}e env=XAUTHORIZATION


SetEnvIfNoCase Authorization "(.+)" HTTP_AUTHORIZATION=$1


# Add security and privacy related headers
Header set X-Content-Type-Options "nosniff"
Header set X-XSS-Protection "1; mode=block"
Header set X-Robots-Tag "none"
Header set X-Frame-Options "SAMEORIGIN"
Header set X-Download-Options "noopen"
Header set X-Permitted-Cross-Domain-Policies "none"
SetEnv modHeadersAvailable true

# Add cache control for CSS and JS files

Header set Cache-Control "max-age=7200, public"

ErrorDocument 404 /oc/core/templates/404.php

`

There also is a .user.ini, which reads

`upload_max_filesize=513M
post_max_size=513M
memory_limit=512M
mbstring.func_overload=0
always_populate_raw_post_data=-1

output_buffering=0

`
Any idea, how to solve that prob?

Thank You so much,

Steffen

Hi,

have a look at the following FAQ. Without the matching logentries to this white page its nearly impossible to guess whats wrong here.

Hi, RealRancor,

thanks for Your reply.

As the owncloud-log is about 10 MB, I firsthand tried a complete new installation of oC 9.1 and a copy of my data afterwards which worked out fine until now.
