I need some support for activating the speadsheet feature in Tiki 15.0.
We use speadsheets in Tiki 12 since several years. Now we migrated two sites running on two different servers from 12.4 to 15.0 and from 13.0 to 15.0
In both cases I cannot view the list of spreadsheets.
I tried to use the feature in the demo site. The Tiki 15 xersion there is 15.0alpha and spredsheets are running well.
I checked my error log and found
PHP Fatal error: Class 'PEAR' not found in ... /lib/sheet/excel/writer/format.php on line 44
I tried a workaround and inserted before line 44 in format.php
Now I could view and create spreadsheets
I tried to import a sheet from CSV, but it failed with
PHP Fatal error: Call to undefined method TikiSheet::setSize() in ... /lib/sheet/grid.php on line 1234
Thank you in advance for any hints
