Well, here we go again folks. This issue seems to be a hassle for multiple persons for many years at this point. Also, for most people, it seems to present itself suddenly, with no conscious changes having been made by some of the blog "victims". (I have started a new topic because the last such post was from 2011 and I don't want to be "buried" in someone else's post that everyone might think has been resolved. Also, the issue that is causing my error might be different than the other posts, because trying the previous posted "solutions" did not help me.)
In my case, for my paupergirl.nowfind.us/evolution blog, the only changes recently made (aside for a new blog post Feb 16, 2013) were some settings in an attempt to eliminate SPAM: I reduced number of links that could be put into a comment to 1 and then I prohibited any links in comments by changing the maximum links to zero. (And, BTW, the "karma" thing is not stopping the posting of comments with a link...though that's a separate issue.)
As with others, I have tried the various suggestions I have found in the forum going back to 2008 or before: Changed "instance" name; rebooted; tried different browsers & computers; increased the "timeout" setting' verified that base URL and URL syntax in the config file was correct (this blog IS a subdomain of nowfind. us & if I change the base URL from what it is, the CSS is not found. Previously, it worked fine with exactly the current base URL setting.).
Please help! This is a serious enough error to cause someone to abandon B2Evolution...If one cannot post to, or administrate a blog...what good is it?
I have changed the debug setting so that I could obtain the debug display. It is shown below. I would be happy to provide administrative login information to a forum "geek" if that is necessary in order to solve this problem. In other words...HELP!!!!!!!!!
