as my previous post mentioned, I have been having no end of troubles with Blogger, so much so, I was thinking of moving over to Wordpress ;-(
this problem seemed to relate to IE and blogger and a few rogue cookies ;-)
for a few days I could not log in - blogger help suggested clearing cache, cookies, etc - so I did that, as well as the suggested workaround to log in and untick 'remember me'. This seemed to solve the issue of not being able to log in, but did not do anything to resolve the issue of not being able to leave a comment.
After following some of the suggestions mentioned in Blogger Help - clear cache, cookies, etc, etc I developed a new problem on Monday - I could NOT LOG/SIGN OUT, in order to log/sign in and untick the 'remember me' option.
After wading through Blogger help, and reading some very helpful posts by nitecruzr, I had a glimmer of hope!
In IE, Tools, Internet Options, Browsing History, I deleted temporary internet files, cookies, internet history AND unticked preserve favourites websites data!
ta da! I have been able to log in and log out, and leave a comment on a blog I have been having issues with for the last two weeks!
nitecruzr has some great information about the nitty gritty of blogging - a lot of it went over my head - but I learned enough to fix my blogger issues.
