Can't access options page

I had this same problem and finally tracked it down to a conflict with the Better WP Security plug-in. If you use that plug-in, you need to disable the “Turn off file editor in WordPress Back-end” in the Tweaks tab.

If you aren’t using that plug-in, search your wp-config.php file for something like this…

define( 'DISALLOW_FILE_EDIT', true );

If you find anything like that, you need to comment it out.

If you are concerned about security, you can turn file editing on long enough to set the Photospace Options, then turn it back off again.

I have no idea why Photospace breaks when this security feature is turned on.

Yes, and therefore doesn’t work in sites where the admin can’t ‘edit theme’ php / css files.

it is caused by this line

add_menu_page('Photospace options', 'Photospace Gallery Options', 'edit_themes', basename(__FILE__), array('photospace_plugin_options', 'display'));

which should be better served by a different capability e.g. edit_theme_options which refers to things like background, rather than edit_theme which refers to the capability to edit the actual theme php / css files

add_menu_page('Photospace options', 'Photospace Gallery Options', 'edit_theme_options', basename(__FILE__), array('photospace_plugin_options', 'display'));

I would propose the developer makes this small change.

Thanks, I’ll look at this for the next version.
