Issues with multisite and plugin

Hi,

i already did exactly the same operation on another platform, and everything was working great. But this time, no idea why, nothing is working and i’m going crazy :slight_frown: really hope you can help me. Basically, i’ve setup a multisite and here comes the first problem. Why trying to login to a subsite (we choosed multisite in a subfolder) we got the message: ERR_TOO_MANY_REDIRECTS. We searched and tried a lot of suggestions in the internet, but nothing helped. Furthermore, another strange behaviour is, when we try to install plugin from the wpmudev dashboard, it does not work, this message appears: “”Installation of Snapshot Pro failed. Most likely reason for this are wrong folder permissions of your wp-contents folder.”” Strange is, on the same wpmudev dashboard, when installing a plugin from the right side, those who are displayed when opening the dashboard, then it works normally. What did i miss?

Can you help me please?

Thanks a lot

Daniel
