search this forum, someone posted his log file, copy its content. or if u have another functional yappari on another n900, go to /home/user/.config/scorpius using filebox . there you will find a yappari.conf textfile. send it to the fone and save it where u'll have quick access to it. using filebox long press the textfile to edit it. replace the phone numbers with yours. also change the cc to ur country zip. save and copy the contents u editted. now navigate to /home/user/.config/scorpius if u cant find the scorpius folder in the .config folder then u will have to create one. in the scorpius folder create a yappari.conf document and long press to edit . paste ur copied contents in it. or u can copy the whole editted and saved yappari.conf file to the scorpius folder. should work like that. restart ur yappari app. if it hangs or shows strange behaviours. reinstalli.
i tried this method myself a couple of times and it works great. 100percent.
