The error message suggests you are either missing or have an older version of log4j in your userlib.
Take a look in your userlib, and if you have several versions of log4j in there, remove the ones with the lowest version numbers.
If you are missing log4j in your userlib then you may need to reinstall any third party modules you have in your application from the Mendix Marketplace and this will hopefully restore the missing file.
