Baloo I don't have messenger downloaded even and mine shows the C (copyright) symbol at the bottom of every page without text next to it. The only way you see text is if the symbol is clicked on then you will see 2018 Company. I don't think it's a conflict with messenger.
Additional indications. I have this problem with Protean, Decorus. So, I think the problem really comes from messenger + popup because I just installed "Lucid" and the key remains ok with or without messenger.
Thank you Chris to confirm because I have the same problem with a key module AQB, they looked and I quote: "You may post there in that discussion that the _t() JS function does nothing for some reason when you're facing the problem discussed. Thus no any js language keys are showing up properly, including the _copyright for example."
So because it affects other modules, it would be nice to find a solution to this problem, thank you.
But this problem has dragged on for more than two months now, I said from the beginning that it is linked to messenger block and that it must be disabled. But, copyrigth is not what bores me the most, it also prevents me from using the AQB module. This module is made to distribute a popup on all pages of the site. And as you can see above, on the page where the messenger block is activated, it makes me the same cinema.
Well it is FINALLY fixed in rc10. We are very patient people! Our members are less so ...
