Update temporary item data not updating

I installed Flexi on an existing site because I needed it for new site features and it was working fine for a few hours; I was able to add an item, fields, etc. I'm now stuck at the dashboard and Update temporary item data will not update, so I cannot access any of the items on the site.

I saw in older posts on the forum that this might be a feature that could be turned off in a future update, is this possible? Or is there a way to force this item to update?

Thank you

Edit:
Flexi 3.3.7
Joomla 3.9.20

Hello

can you provide access ?
i would like to see this, as this should not happen,
i mean you should only have to click once on the button

and i will look at it ASAP

What is your email address to put on the account?

Thanks

EDIT:
Disregard, I have it from another issue. I will PM you

Hello

the backend is protected by apache htaccess password, i would need this too

Hello

ok i have the access now

probably will look at it today, otherwise tomorrow morning

Hello

it is good now

The column 'title' in PREFIX_content DB table was VARCHAR(800) instead of VARCHAR(255)
which is not default Joomla DB schema

we do not check for this when verifying FC temporary data table ... as it is not expected to be different than default
