SID-01544: Twiki : WYSIWYG Editing Errors

Status:	Answered	TWiki version:	5.1.1	Perl version:	5.8.4
Category:	CategoryEditing	Server OS:	Solaris 10	Last update:	13 years ago

Hi Team,

We had performed upgrade last week and had run into some issues . One of which was that editing in WYSIWYG mode does NOT work unlike raw edit.

It reports the following error everytime we attempt to save after editing using WYSIWYG plugin/mode.

Base class package "HTML::Parser" is empty. (Perhaps you need to 'use' the module which defines that package first, or make that module available in @INC )

Perl is installed at /usr/perl5/5.8.4/bin/perl

(PROD)emarkets@ap-em6p-a:~$ which perl /usr/bin/perl (PROD)emarkets@ap-em6p-a$ ls -la /usr/bin/perl lrwxrwxrwx 1 root root 23 Jul 3 23:08 /usr/bin/perl -> ../perl5/5.8.4/bin/perl

Also , when we test MTHML::Parser , it returns the following output

(PROD)emarkets@ap-em6p-a:~$ /usr/bin/perl -MHTML::Parser -e 0 (PROD)emarkets@ap-em6p-a:~$

Can you please advise how to fix the issue ...

Thanks Clive

Discussion and Answer

Furthermore , please let us know if it is because we have not created LocalLib.cfg in the bin folder defininig the Perl Lib Path just like belows ( as observed on our old twiki 4.1.2 folder ) :

(PROD)emarkets@ap-em6p-a:/me01/apps/emarkets/twiki-home/twiki/bin$ cat LocalLib.cfg | grep Perl @localPerlLibPath = ( '/me01/apps/emarkets/twiki-home/perlmodules','/me01/apps/emarkets/twiki-home/perlmodules/i86pc-solaris-64int' );

FYI , the http.conf has the following section for Perl settings

# mod_perl settings # This matches all lower-case file names, except # those starting with "configure" <FilesMatch "^(?!configure)[a-z.]+$"> SetHandler perl-script PerlResponseHandler ModPerl::Registry PerlSendHeader On PerlOptions +ParseHeaders </FilesMatch>

We had tried to comment the above section related to Perl Settings after we received the following message ( Internal Server Error ) and apache logs indicated

[Sat Sep 29 12:04:49 2012] [error] [client 10.154.105.187] failed to resolve handler `ModPerl::Registry': Can't locate ModPerl/Registry.pm in @INC (@INC cont ains: /lib /me01/apps/emarkets/twiki-home/twiki/bin /usr/perl5/5.8.4/lib/i86pc-solaris-64int /usr/perl5/5.8.4/lib /usr/perl5/site_perl/5.8.4/i86pc-solaris-64 int /usr/perl5/site_perl/5.8.4 /usr/perl5/site_perl /usr/perl5/vendor_perl/5.8.4/i86pc-solaris-64int /usr/perl5/vendor_perl/5.8.4 /usr/perl5/vendor_perl /me0 1/apps/emarkets/apache22) at (eval 4) line 3.\n

Though twiki worked fine , we were not able to edit in WYSIWYG mode

Error again reported in apache logs is as follows :

Base class package "HTML::Parser" is empty. (Perhaps you need to 'use' the module which defines that package first.) at /me01/apps/emarkets/twiki-home/twiki-5.1.1/lib/TWiki/Plugins/WysiwygPlugin/HTML2TML.pm line 44 BEGIN failed--compilation aborted at /me01/apps/emarkets/twiki-home/twiki-5.1.1/lib/TWiki/Plugins/WysiwygPlugin/HTML2TML.pm line 44.

Hi Team ,

Looks like we are now able to edit in WYSIWYG mode after we created a LocalLib.cfg file in the bin folder and included mod_perl settings in http.conf ( uncommented ) .

We no longer get the errors in apache logs .

Can you please have a look @ our other queries posted ...

Thanks again ...

Thanks Clive
