Hello there,
Thank you for your support. I was experiencing a conflict with another plugin, for translating my website in three languages, which is Polylang. By deactivating Polylang, everything is coming back to normal in ProfileGrid.
Still I’m working on ProfileGrid to be correctly integrated into a multilingual website, with ProfileGrid working in english language from his side. The integration is in process, I might let the community know when I’ll succeed. Multisite option looks also like a good solution, then ProfileGrid could be separately translated in each language for a better experience on the website.
Thank you again for your active support!
Olivier
