Export XLSX Error

[tanya]

In the latest version Espo/Modules/Advanced/Core/Report/ExportXlsx.php is different and uses other library. Clear Cache, try again and check the log

Could you upgrade Advanced Pack? When did you buy this extension?

[mfonsatti]

P.S. it is prohibited to share the code from Advanced Pack by license.
