Daniel is right.
To be complete:
1>When I go to comment I get a fatal error
2>When i upload from the front end I get this message: Wrong image format.\nWe will redirect you to the upload screen
5> When I went to turn off the comments in the back end it did not respond.
These are all fixed in Nightly Builds. Last changes I made about ten minutes ago, so probably available tomorrow.
3> I receiver this warning message: Warning: Missing argument 1 for mosPageNav::writePagesLinks(), called in /home/meigtwoc/public_html/components/com_rsgallery2/templates/semantic/display.class.php on line 1388 and defined in /home/meigtwoc/public_html/includes/pageNavigation.php on line 92
4>Slideshow one generates a fatal error.
These ones I am unable to verify at the moment.
Can you explain 4 a bit more in detail?
Cheers,
