yes it seems also a buddypress bug because i verify also yesterday that it is the same problem with the default theme …
I try with “W3TC” or “Redis Object Cache” (By Till Krüss ) plugin and the problem is the same (seems not depend of the cache plugin you use) and important the problem is the same if you use Object cache on Disk or Redis …
Inform me if you post on budypress trac (not do it 2 X)
Your are right ! the problem is the same for the members/groups directory:
I discovers the the title is the first one that is put in cache
If i purge the cache and reload first the french page, the title is the french version in all languages
if i purge the cache an load immediately the english version of the page the title is the english one in all languages
And remember only if object cache is active and only for these index pages (all other pages, post, are switching correctly the title language
(but Redis object cache is necessary in such website)
Waiting your answer
I was disappointed by your answer and test, because in my production site the problem was still there.
So i test again in the development site, like you do it, and confirm that this is working and the new gallery appear in the list with the component “Sidewide”.
I try to discover what could be the difference between our production site and our dev site and finally remember that the only difference was the “Redis object Cache” plugin to improve the performances.
I try to deactivate this plugin and create a new gallery and it appear correctly with the component Sidewide !
I activate again the Redis plugin after the Gallery creation and it stay correctly as Sidewide.
So remember that the “Redis Object Cache” plugin can create conflict with your gallery creation system …
If you find the reason of the problem or a solution please inform me …
Best regards and thanks a lot for helping us to solve this issue
