A) Should i install the WORDPRESS PLUGIN:

https://wordpress.org/plugins/paid-memberships-pro/

IF YES, is the free version  enough ?  or should i install a paid version ?

Yes, the free version is enough. So if you have selected this membership plugin then you should install the free plugin and the integration addon:

• The free Paid Membership Pro: https://wordpress.org/plugins/paid-memberships-pro/
• The integration addon: https://gvectors.com/product/wpforo-paid-membership-pro/

But is the  Wordpress Memberships pro  necessary ?

if yes is the free version enough ?

I'm really sorry but you cannot use more than one membership integration with wpForo, we can refund other addons, please choose the one you want to integrate. Currently there is no way to integrate all membership plugins with wpForo.

is paid memberships pro   necessary ?

But i'm in confusion:

A) Should i install the WORDPRESS PLUGIN:

https://wordpress.org/plugins/paid-memberships-pro/

IF YES, is the free version  enough ?  or should i install a paid version ?

B)     MemberPress -  Paid Membership Pro -  Groups  and Suremembers

I need all those plugins   (memberpress is interessant,  Groups is very interessant, and paid membership pro  could be in fews months interessant).

and i need suremembers too,

So  should i install all   or only one  ?

thank you

Please DO NOT use lots of membership plugins toughener.

You should use one of them:

• MemberPress
• Paid Membership Pro
• Groups

They are all about paid membership feature, why are you installing lots of membership plugins?

Just select the one you want install it, then install the Integration addon for wpForo. Please deactivate all membership plugins and use juts one.
