i have 3 joomla sites. after last update (7.0.26) I have some troubles with its.
- login take too much time.
- I can't login jommla administrator page. username or password error. but it is correct. I just added ? end of the url, page opening.
- I can't logout Joomla administrator page.
I know this is not Joomla support. but it began after last update (7.0.26).
