Drupal Theme not Saving, keeps blinking the sign in overlay box

Hello,
Sorry for the inconvenience. We have found the problem. It's related to a security update in Google Chrome v80.
If you are using Google Chrome, try this:
1) navigate to:
chrome://appcache-internals
find your website and click on 'Remove Item'
2) navigate to:
chrome://settings/clearBrowserData
select 'Cached images and files ' and click on 'Clear Data' (please don't check other check-boxes).
3) Reload your Themler Editor.
Some users have reported that complete re-install of Google Chrome solved the issue.

If you are using the Desktop version, then:
1) close Themler
2) open Windows Explorer and type %LocalAppData% in the address bar
3) find & rename Themler directory
4) start Themler again

Happy to report that the second set of instructions under "Desktop version" worked. I tried the first set of instructions, but couldn't get passed step 1. Also, I reinstalled Chrome, but it still did not work.

It took a while for Themler to reopen after I renamed the directory, but it worked. Thank you.

It works... Untill login is required again.

Hello,

Doesn't it work with log out and then log in again in Themler desktop or online?

Sincerely,
Nettie

Sure. But next time login session are expired, the problem occurs again

Does it behave same in firefox?

I can confirm too that this happens each time the login session expires.

Please, test firefox and incognoto mode in Chrome.

Hi Gina,

The problem is that when I close Themler, I am logged out each time. So I can never export or save a theme this way.

I only use Desktop (can't run it online, it doesn't work due to server permission issues) so I can't test other browsers than Chrome.

Also, as soon as I hit the Export button, it logs me out. The instruction above worked once but now it doesn't anymore.

Please advise on how to regain use of Themler again... Thanks.

For anyone looking for a (temporary) solution: I decided to undo the latest Chrome update so I can regain use of Themler. It may not be recommended but if Themler is of strategic value to you, it will restore functionality if you're using Themler Desktop on Windows 10.

Here is a working instruction: https://www.reddit.com/r/chrome/comments/9hhdbr/can_i_downgrade_my_chrome_version/

Please note that the Chrome version from before this update, is now this one for 64bit: https://www.slimjet.com/chrome/download-chrome.php?file=files%2F79.0.3945.88%2FChromeStandaloneSetup64.exe and this one for 32bit: https://www.slimjet.com/chrome/download-chrome.php?file=files%2F79.0.3945.88%2FChromeStandaloneSetup.exe

After downgrading Themler will work again.

I can confirm that the issue is related to new security policy in Chrome v80 or above.
We have released one more fix to our server two days ago, you can test it if you clear the cache as suggested in my original reply once again.

Hi,

This issue is still persisting. The login overlay keeps popping up, preventing the saving of themes.

I completely removed and re-installed Themler, I did the original steps again, to no avail.

I'm using Themler desktop.

I've now removed Chrome from my system, after reading a useful comment by peter80 here: https://answers.themler.io/questions/198358/themler-blinking-by-save-importet-wordpress-theme-not-save-possible.

This triggers Firefox (developer edition, in my case) to load Themler and then Themler works.

I signed out three days ago and today I signed back in and had no issues. Following these steps worked for me:

If you are using the Desktop version, then:
1) close Themler
2) open Windows Explorer and type %LocalAppData% in the address bar
3) find & rename Themler directory
4) start Themler again
