The other day I went to export a section of the database to Excel and it would not work.
Did you export to a file with the .xls or .xlsx extension? It should work if you use the .xslx extension.
Later I tried to save a list of records to a PDF and the list consisted only of one record when there should have been at least 1000.
Did you by any chance use the "current records" option instead of "Records being browsed"? That would save a PDF of only one record.
I tried to export as xlsx and it wouldn't work. The PDF was set for records being browsed.
