Hi…
I did follow troubleshooting steps but nothing seems to work.
Step 1.) I added the twitter card code under head section in the template. I got the same error.
Step 2.) Then while researching more, I changed robot.txt section as below (I had earlier put the sitemap details in the box):
User-agent: Twitterbot
Disallow:
User-agent: *
Disallow: /
even this didn’t work.
3.) Then I read somewhere that I should add the codes under <b:includable id=‘post’ var=‘post’> and keep the search description enabled.
Tried this also but even this was throwing the same error.
4.) I noticed that after saving the template each time, when I went back to Edit HTML page, the codes were not showing up even though I was able to save the theme without any error.
5.) I added codes again > saved it > clicked on preview theme. It shows:
The widget settings in widget with ID AdSense1 aren’t valid. An internal error occurred. Please try again.
Error 500
Don’t know what else to do. I am naive when it comes to coding… please help.
