The second use of the user, once again through the Web landing, it returned to normal.

Prompted me to see the log file, yum install owncloud, log file location where? Ask this question, how to solve?

owncloud version:9.1

(I am Chinese) Simplified Chinese error:

Which browser? And which specific ownCloud version? Newest 9.1.x?

Browser: Chrome and Mozilla

ownCloud version;ownCloud 9.1.1 (stable)

Would upgrade to the newest 9.1.3 first, there were a couple of fixes in the first login handling. Mostly for IE11, but might as well effect your case.
