Viewing a history listing
ULS does not worked now. Changing interface language trough user preferences also does not worked (new value is saved in preferences, but interface language is still in old language).
Worked only "&setlang=" option in the URL.
This is TWN local problem, in Wikimedia wikis all worked correctly.
PS: In the dev. console i saw two critical errors:
- freegeoip.net/ Failed to load resource: net::ERR_BLOCKED_BY_CLIENT
- analytics.js Failed to load resource: net::ERR_BLOCKED_BY_CLIENT
Maybe these is related with this issue.
