Bet Hannon on "Mutlisite - Plugin work and not"

Hello

I am on localhost for a website. I have create a multisite, one maindomain, one subfolder.
So I created the second website using the first one. And everything went well: but some plugins do not works quite well. All plugins works fine on the main website.

WD slider and Photo album works fine in the main website but I cannot create a slider or albums in the second one.
All in one calendar has all the events from the main website, but it cannot create the calendar page for the events (there is no events).

However the plugin Caldera forms works perfectly in both websites.

I would love to have some help on it, because I am stuck.

Thanks

In multisite, there are some plugins that work when "network activated" (from the network admin dashboard) on behalf of all the sites in the network. Akismet is one, for example. Or WordFence.

But other plugins only really function when the are "single site activated" from within the Plugins dashboard of each site. Forms plugins as well as image/slider/gallery plugins would be an examples of this -- each site really needs to run its own settings of each plugin. While they "may" function ok for now, network activated (Caldera forms), over time and with more sites, it may affect performance, OR, you will discover that users in one site can make changes you don't intend.

Are you trying to run some of these plugins as Network Activated?
