Answered After Update to 2.6.5 Texts in Backed missing: © 2005-

Hi - what a day...
Well but after doing an update to an old site i have problems in backend. On Login Page i see this:
© 2005-[[+current_year]]
and in Backend all the "texts" in the header that show the version and stuff are missing. I just see the modx logo with no text like version number... rest seems to be working fine.. i uploaded all the core files again - didn't help - no erros in console... can anyone give me a hint?
Thanks!
Jonas!

Hi Jonas,
[[+current_year]]- one plus sign inside? If so it looks like a placeholder... maybe some time ago custom snippet code was implemented so that added placeholders to your pages and it was broken during update. It's hard to say what's wrong remotely, if I could check it I can say you more accurately what was missed
