How big is your web?
While there is no limit to the number of files., or total size of
website, that *FrontPage* can manage, some systems do have limits,
especially web servers that impose time limitations on processing web
requests. This will include the "Recalculate Hyperlinks" command
(seen as "Processing Web Updates") on the server that automatically
follows every publish. Your web may be too big for the server to
process - often this results in the "Time Out" or "... could not
parse" errors. It would be a good idea to break the web into subwebs,
where each subweb can be published individually, and thus considerably
reduce the processing load on the server.
Note that since a subweb is an independent web, you will have to
create and apply navigation, themes, include files, shared borders, or
DWTs for each subweb.
