when installing or upgrading modules i sometimes come across errors statings that there is a 'Failed open file' and that XOOPS was 'unable to write to main menu' and the module's admin icon didnt show up (at the left of admin page).
Luckily it can be fixed by deleting the adminmenu.php under the cache directory and have XOOPS regenerate the menu.
does anyone have the same problem?
