Did you test this with a default WordPress theme?. Please switch to a default theme and let me know if the problem remains.

I wrote that it is not the default theme.
This can be with the Bootstrap framevork?

Hello Zink1,

Please check your theme or plugin conflicts. You can disable all your plugins except User Frontend and switch to a default theme of WordPress like- Twenty Twelve, Twenty Thirteen, Twenty Fourteen and let me know the results.

Thank You ??

With the default theme the plugin works correctly. What could be the problem? Requires setting the file css or something else? This can be with the Bootstrap framevork?

Hello Zink1,

The theme you have need to do some tweaking. You have to setting css what suit you.

Yes, bootstrap framework can responsible for cause this deviation for theme.

Thank You ??
