As of WorkflowGen 7.22.0, the log level values for the GETUSERSFROMDIR, MERGEFORM, SENDHTTPPOST, and RESTAPICLIENT workflow applications have changed to 0 for no logs (default), 2 for information, and 3 for debugging.
You can set (or reset) the log levels by updating the values of the following web.config parameters accordingly:
<add key="GetUsersFromDirLogLevel" value="" />
<add key="MergeFormLogLevel" value="" />
<add key="SendHttpPostLogLevel" value="" />
<add key="RestApiClientLogLevel" value="" />
