I have many sites in WPMUDEV, using various hosting companies. I have no problem updating plugins on any of them, but on some sites, I cannot updates WPMUDEV plugins.
For example, babyliss.se. I cannot update plugins from the Plugins page, nor from WPMUDEV hub.
This is the error I get:
Error in Swedish :
Uppdateringen misslyckades: Uppdateringen av tillägg misslyckades. » Uppdateringen av tillägg misslyckades.
Translation to English:
Update failed: Update update failed. »The extension update failed.
I updated the dashboard plugin via FTP, and that worked. I have 6 more WPMUDEV plugins and it is a bit time consuming to do it via FTP every time. And for several sites.
