Hi Pramod. In the first instance can you try running through our normal troubleshooting steps?
- Ensure that your Modern Tribe plugins are up-to-date and in-synch – for instance if you are using The Events Calendar 2.0.10 you must also be using Events Calendar PRO 2.0.10
- Deactivate all other plugins
- Change your theme: select a default, unmodified theme such as Twenty Eleven or Twenty Twelve
- Now test to see if the problem has been resolved
- If it has, reactivate everything one-by-one until the problem returns (it may not) and take note of whichever component (your theme/a plugin) seems to cause the problem
Thanks!
