Hi Molly,
What kind of error or messages are getting in your logs ? Upgrading the excel importer may bring new jar files and bring you other errors as well. You may have duplicate jar files in your userlib. This is the most observed error in excel and exporter module. I advise you to check your userlibs and delete the old and duplicate one. Otherwise , you can extend timeout limit for the excel importer.
Hi Molly
Agree with Yasin’s proposal to check your .jar-library-files. As an extra: when you have to upgrade your Excel Importer module, there are other Marketplace modules that need updating as well (cfr. MxModel Reflection):
If these steps don’t cut it for you, please edit your question with more context and debug information. Thanks!
Kind regards,
Leander
