SiteBuilder hangs while "page loading" again

[estudiol]

Sorry to raise this again, but SiteBuilder won't let me edit my site (again). It hangs on the "Page loading" screen. I presume the files/database/whatever have become corrupted. Is there any way I can fix this myself? I don't want to lose the site contents unless there's absolutely no alternative.

This usually happens when you've put some sort of custom HTML or script in the sitebuilder.

I would refrain from doing that.

Thanks, but that's not it. I only used the standard sitebuilder functionality. Not even any custom HTML, definitely no custom scripts. Is there some way to delete or reset the system from File Manager? I can open that OK.
