unserialize(): Error at offset 65525 of 65535 bytes ... sc_unserialize.php linha: 20

Goodmorning.

I’ve also sent the request to NetMake, but days will pass before they respond for support.
Therefore I also try here in the forum.

Since this morning when I go to save any ‘internal library’, with or without editing, I get this error even if ‘it seems’ that it was saved correctly.
The popup window opens and clicking on the link appears:


unserialize(): Error at offset 65525 of 65535 bytes | Script: C:\php\WTServer\WWW\scriptcase8\devel\lib\php\sc_unserialize.php linha: 20

The thing shakes me a bit, as usual, being a project many apps (grid, form, control) and several internal library!

Scriptcase vers. 8.1.067, installed in local windows server 2008 R2, with db mysql (not sqlite).
Scriptcase reinstalled a couple of months ago for server changes, worked ‘normally’ until today.

Thanks to those who will help me to understand how I can avoid!
