Install pydio 8.0.2, community edition, centos7, php 7.2.2, pydio 8.0.2
I tried to install pydio 8.0.2 and everything on the check requirements page was O.K. and when I tried to install it I received the following error:
count(): Parameter must be an array or an object that implements Countable

Hi,
could you look at your php logs,
your error is related to php so it should be either about configuration or a package missing.
did you install all the php packages, you can check them with `yum list installed | grep php`
and show me the list.

Hi,
could you look at your webserver logs, redo the error and then show me the last lines of your webserver `error.log`.

Hi,
could remove and reinstall php, go for the 7.0 version and try with it.

No…it’s too much trouble to uninstall/install/configure again. I will search for another web file manager.
Thanks for your effort though!
