Seems like SP is not installed properly. AFter installing the sp you need to wait for some time till you restart the instance. Anyhow Go to package manager and see if there are any package which is uninstalled. If so install the same. Otherwise as a quick turnaround clone from another instance. I am not sure in which stage the current instance, file a daycare so that we can take a look.
Thanks,
