I have installed Joomsef 3 component with Jomsocial (2.1.16) extension.After installation I found 2 problems.

1)when I checked the front end jomsocial link it showed me blank page first time and when I tried refreshing page 2 to 3 times then it starts loading.I found this problem with other jomsocial pages and with other extensions (k2 and moset tree) as well. any idea?

2) After login when i checked the profile links(e.g my profile , photos , videos etc) it shows profile navaigation links with blank page.

I checked all the configuration and everything seems fine.I also re installed the component and extension but same result.Does anyone know what could be the problem? or any solution?

site is based on joomla 1.5 platform and previously configured with sh404sef component. can this be a problem?

Thanks in advance.

Hi,
Previous installation of sh404sef should not be a problem.
Blank page usually means some PHP error. Please check your server's errors log file or enable error reporting on your website and post the error reported.

Thanks dajo.It really helped.

Problem was with the router file of one of the extension which created errors. I found the errors when I enabled error reporting.And fixing errors and then cleaning cache solved the problem.

Thanks a lot.
