I've successfully resolved a similar issue for another customer using the following solution:
The problem likely stems from a discrepancy in the oracle.data access file or version specified in the web.config file.
To rectify this issue, please follow these steps:
- Verify the version of the DLL in the 'axpertweb->bin->oracledataacess.dll' file. Ensure it matches the version specified in the web.config file.
- If your database is Oracle, copy the DLL from the Oracle folder and paste it into the bin folder. Update the version in the web.config file accordingly.
