My blocks disappear during the "update" of the page.

Hello,

I have two problems (bugs) including a major one.
I work with WordPress 5.4.1 with the theme Enfold (enfold-startup) version 4.7.4
I work locally.

Problem 1 / I saw that there was an update to the theme (4.7.5), but I don’t have access to it from my WordPress. Indeed, for this it is necessary that the purchase code is registered. But I can’t do it (“Enter a valid Envato private token”).

This is the answer I was given:

“Last time we checked the token we were not able to connected to Envato:

Purchases could not be accessed
Username could not be accessed (needed for your information only)
E-Mail could not be accessed (needed for your information only)
Following errors occured:

Purchases: Your private token is invalid.
username Your private token is invalid.
email Your private token is invalid.
Purchases: A problem occured accessing your purchases. Unable to check for updates. ”

I’ve been trying for two days, without success.
So I can’t update my theme.
But this is “not too serious” …

Problem 2: MAJOR BUG /
In page editing, when I work on a page (the HOME page for example), when I modify a block and then I “update” the page, this removes all the blocks which are below , and sometimes even the ones above.

This does not do with all of the elements, but with some only.
I’m constantly going back on “revisions”.

Impossible to understand what is wrong!
I’m a bit devastated, because this theme suits me perfectly, and I have a limited time to make my site.

Do you have a solution please?
Thanks for your quick feedback.

Very cordially,

Thierry
