wordpress gives error 500 when this plugin is active with php7.0:

when the plugin is deactivated it works great.

Do you have your xml extension built-in?

Can you be a bit more specific? It runs on Ubuntu 14.04.4 and nginx/1.9.15

Hi!

What Viktor mean is that your problem is not PHP7 as the function xml_parser_create() is compatible with PHP7 but a lacking PHP extension. This extension is enabled by default. So it should be there unless removed intentionally. You should check that with your host provider.

I wonder if the strange error I get (only on the backoffice):

Uncaught Error: Call to a member function translate() on null in /path.to.my.wordpress.installation/wp-includes/l10n.php

is also somehow related to PHP 7.0? Note that I’m using a beta version of WordPress, so maybe this is the real cause of that error…

I found this:
https://stackoverflow.com/questions/35593521/php-7-simplexml
which looks similar and seems specific to Ubuntu.

@gwynethllewelyn

I don’t think PHP7 is the cause of your issue. You should try with a default theme and without plugins to see if your problem is still there.
