I have been trying for some time to get Open Live Writer (OLW) to work properly with Google Blogger. I could actually connect and post, but one of the best features of OLW is the facility to download the blog theme. This enables you preview your post in draft mode, before you finally upload to Blogger. I use this with my WordPress Blog (unashamed plug there) and it worked without any issue. However I simply could not get OLW to download the relevant files. I tried raising the issue with the OLW forum, but that did not help. The answer came in an unorthodox way!
I had a problem with my Google account password. Somehow it needed to be reset. I managed to reset to a new password, but then found a problem with Outlook 365. I was now unable to connect Outlook to my Gmail. Every time I tried to enter the new password, it failed. No passwords, old or new were being accepted. I tried removing my Gmail account and re-adding it, without success. I began the process of adding Gmail to my Outlook.com. It took a Google search to find out the issue. It seems, that back in 2014 Google started to block, what it considered to be unsecure logins. This was the problem and I needed to amend a security setting. I needed to “Allow less secure apps” to be ‘ON’. Problem with Gmail/Outlook sorted. The relief was massive. I really did not want to have to use Outlook.com as my main email client for many reasons.
It then struck me! “Hmmm,” I thought. “I wonder if that is the problem with downloading the theme for Blogger?” It seems that it was. So there we are. All sorted.
