Hi, I tried to run the latest svn version of TWiki and found a problem when I try to edit a document with inserted images. This is the message in the error log: [Thu Jun 28 09:10:47.245723 2018] [cgi:error] [pid 6471] [client 127.0.0.1:56488] AH01215: [Thu Jun 28 09:10:47 2018] edit: Use of uninitialized value $value in transliteration (tr///) at /var/www/twiki/lib/TWiki/Prefs/PrefsCache.pm line 257.: /var/www/twiki/bin/edit, referer: http://localhost/do/login/LoraProject/TheNopLoRAWanStarterKit?t=1530169840;nowysiwyg=0;origurl=/do/edit/LoraProject/TheNopLoRAWanStarterKit%3ft%3d1530169840%3bnowysiwyg%3d0 After this error the wysiwyg editor does not start.

Discussion and Answer

Not sure why an undefined value is passed on to this function. Could you try to add this on line 257 of lib/TWiki/Prefs/PrefsCache.pm just before $value =~ tr/\r//d; :

$value = '' unless ( defined($value) );
