Hello @nohsharon,

Please give us full access to wp-admin panel, not just to “My Account” page.
Are you getting any issues with Visual Composer elements?
Also provide us with FTP credentials.

Thank you.
Regards,
Eva Kemp.

Hello @nohsharon,

Unfortunately we still can’t connect. There is an error:
Error: Authentication failed.

Please add this code in .htaccess file:
```
<IfModule mod_headers.c>
   Header set Access-Control-Allow-Origin "*"
</IfModule>
```
And check your site after that.

Regards,
Eva Kemp.

Hello @nohsharon,

At first you reported this error on your site:
Uncaught SecurityError: Failed to execute ‘toDataURL’ on ‘HTMLCanvasElement’: tainted canvases may not be exported.

Is it resolved now?

Do you mean that now you’re getting “time out” errors on your site?
Could you please be more specific what problem you’re experiencing?

Thank you.

Best regards,
Jack Richardson.

HI Jack
I guess I should start a new support thread. The reason why I added this new error ticket on this same ticket is because Eva suggested that we update our plugins and theme. But we continue to have issues related to the theme.

The original error message – Failed to execute ‘toDataURL’on ‘THMLCanvasElement’:T doesn’t seem to be an issue anymore.

Please let me know if I should start a new ticket.

Thank you,
sharon
