Just upgraded to Machfrom v11. Having an issue when trying to export data to Excel. It just gives Internal Server Error 500. Exporting to CSV and TXT work perfectly though. Any suggestions is greatly appreciated.
I saw a similar question, same issue - the solution was simply to use .csv (which can be opened in Excel and therefore saved as .xlsx from that application). The other post also stated the error may occur when there are many records being exported.
