It would be helpful to post a fix here and/or correct the problem. I found this thread when searching for a solution to this issue. We have exactly the same problem - a website that has display data from many Google Sheets for several years no longer works and Table_Master reports valid URLs as invalid. It may well be Google’s fault, but it still needs a fix from WiX.
e mas’ala ke pehle Google Sheet website par dikh raha tha aur ab achanak se nahi mujhe bhi kisi aur thread mein nazar aaya tha. Wahan aik user ne report kiya ke “HTML component with Google” mein sheet preview mein theek thi, lekin publish hone par blank nazar aati thi, jaisa ke html-component timing ya load sequence related ho sakta hai Community Support Forum | Wix
Hey!
This is a Known Issue and something that needs to be solved by Google Support. Please reach out to them as noted in this Known Issue - Spreadsheets Not Displaying in Table Master Within the Editor (URLs Marked as Invalid) | Help Center | Wix.com
Hey Noah,
This is a half-known issue - more work needed! Yes, the numpties at Google have changed something (again, since I seem to recall this happening before) but Wix will need to update their coding to reflect the change before functionality will be restored. Google Support won’t ‘solve’ this for you / us - it’s now a Wix issue.
