Doesn't work with PHP 7.1

[The_Miner]

Hi all,

my provider wrote a mail, that PHP 5.6 is old and will not be supported in die next time.
So I changed the PHP version so 7.1 and get a blank white website. When I'm switching back to 5.6 the Website is working again.

Used version: 1.6.06.

I hope you can help me.

It is probably being caused by one of your plugins.
Create a disabled_plugins folder. Move all the plugin folders (except the upload_xxx plugins) into the disabed_plugins folder.
If the site now works okay, move them back one at a time until you find the one causing the problem.

Also, follow this advice for your theme:

Thank you, I worked.

Could you please tell us the plugin that was causing the problem?
There may be a replacement for it here or here.

Truth be told,- it deleted all of them and installed only the upload plugin.
