    Hi

    I’ve a blank screen if I try to open the forum pages [http://nccr-planets.ch/forum/planets-forum/], this are since I’ve update to version 4.7 from WP. I’ve try to deactivate all other plugins, but it still not works. And also change to another themes give me the same result. The only possible reason I could make are a downgrade from the WP (I’ve test this on my test system and he works). What can I do that the forum displayed on the current WP version?

    Thanks for help!

    4.7/4.7.1 and bbpress 2.5.12 work

    If you have these then :

    1. what php version are you running?

    your host provider can answer this

    or you can install

    https://wordpress.org/plugins/display-php-version/

    If it’s php7 then come back

    otherwise

    It could be a theme or plugin issue

    Plugins

    Deactivate all but bbpress and see if this fixes. if it does, re-enable one at a time to see which is causing the error.

    Themes

    If plugins don’t pinpoint the problem, as a test switch to a default theme such as twentyfifteen, and see if this fixes.

    Then come back

    Hi Robin

    Sorry for my late answer. I’ve test it with php version 7.0 and now I’ve also a blank screen with the following message (when I activate the wordpress debug):

    Hi Robin

    Today I’ve simply reinstall (deactivate & delete before, and then install) and now it works. I’ve no idea why, but now is fixed.

    Thanks, Ulrich

    Hey great – glad you are fixed

    It always amazes how many times a simple ‘off and on again’ works !!
