Hi Turnermm,
thans a lot for the prompt response! I am more user that developer :), but I try to bring the correct answers (pagename replaced with "*" ) ...
Here are the answers:
Problem 1: (cannot save page)
> It looks like a javascript issue, so what does the browser show in the javascript console?
By load I see in the console:
Refused to load manifest from 'https://***.com/dokuwiki/lib/exe/manifest.php'
because it violates the following Content Security Policy directive: "default-src 'none'".
Note that 'manifest-src' was not explicitly set, so 'default-src' is used as a fallback.
By press save I see
js.php?t=bootstrap3&tseed=ea283e15ad72e87478c8fd0659abad6a:1
Uncaught Parse Error: <a class="wikilink1 curid" data-curid="true" href="/dokuwiki/doku.php?id=*:*"
title="*:*">go to top</a> | <a class="wikilink1" href="/dokuwiki/doku.php?id=*:start#system_configuration"
title="*:start">back to Index</a> | <a class="wikilink1"
href="/dokuwiki/doku.php?id=*:start" title="*:start">Wiki start page</a> ]</p>
and link to
js.php?t=bootstrap3&tseed=ea283e15ad72e87478c8fd0659abad6a:1
> You say these are 'old' pages. What about new pages.
New pags are all OK, but I suppose that it's about some tag which was used in old pages and which I do not create in new.
I'll try to find out which tag is it.
> Also, the problem can be originating in your bootstrap3 template. Have you updated it to the latest release?
as I see the link to bootstrap3, you are right, however I am not owner of PHP installation. Can you say, how can I check the bootstrap version? I can order the update if it's necassary.

> And are you using the latest ckgedit?
yes ... at least dokuwiki propose no newer version.
Problem 2 (erase page and write "false" instead by switch to another editor)
I see just very quickly something in the console and than it's replace the page and in the console I see
Refused to load manifest from 'https://***.com/dokuwiki/lib/exe/manifest.php'
because it violates the following Content Security Policy directive: "default-src 'none'".
Note that 'manifest-src' was not explicitly set, so 'default-src' is used as a fallback.
Thank you again for your help!
