Some options are not saved in modules and other parts.

Hi,

I found that some but not all options in eg. CGGoogleMaps, Blogs and other places are not saved.
What is strange that in Blogs the "Number of entries on a page:" changes when i view the number of entries, but this is not represented in the settings tab.
When i change eg. "Textlink to show for complete entry:" this works ok.
Also some dropdowns work and some not.

I went through the system information page and all is flagged green.
CMSMS version is 1.5.2.

Because the problem is not consistent i wonder what it can be?

In the attachment relevant system info can be found

Thanks,
