I use Narga's guestbook module and from few week someone have started to sent some spam messages. There is an automatic method to prevent this messages? in example in my case the sender is ever the same or at least have the same e-mail.
After the update to 2.0.9.3 version of XOOPS image manager stop to working. when I try to upload an image, after the click the submit button, the seem that is been send to server but after this appear an error page.
if your server have phpMyAdmin or you can access to MySQL server with a console you can prepare a macro and insert username and password, crypted with md5 function, in users table.
The standard template for recent news block (template/news_block_new.html) load also some images in a style bock, at the start of template during definition of css style.
You can change the images used for background or modify the images.
