Problems with preview and image attributes

[Cutter]

Hello!

I have two problems with CMSMS:

1°/ I have installed CMSMS on a remote host running MySQL, Apache and PHP (don't know the version number, though). My problem is that, when I want to preview a page in the Edit Content page, the following message appears in the field dedicated to show the preview: "Error: Cache file: cmspreview7meDHK does not exist." The code after "cmspreview" is random and changes each time I hit "Preview". I'm using the default WYSIWYG editor. The server on which I installed CMSMS has PHP Safe mode activated. I hope this is not the cause of my problem, because apparently I can't change that.

2°/ I'm using FCKeditorX. When I insert an image, a dialog box offers to set some attributes for the image, like size, alignment etc... My problem is that the "Border, "HSpace" and "VSpace" image attributes doesn't have any effect on the result. Width, Height, Align work OK though. I noticed that this problem doesn't only occur on my installation of CMSMS but also on the public demo hosted at opensourcecms.com. What should I do about that?

Please help.

Thanks in advance.
