Hi Mate,
This is common issue in iApp. You need to delete the iAPP configuration manually from the .conf files and load it.
- Copy the .conf files to your local system. Open it with notepad++ and find the configurations for your iapp.
- Delete it manually from the conf file.
- Take backup of the existing conf file.
- Copy it to the F5 and run load tmsh verify
- If verification success, run the command load tmsh (filename)
Make sure that you have deleted everything from the conf file before you load the conf file.
This is not a recommended way but only option to get out of this kind of problems at this point of time.
Let me know if you need any help on this.
