Shortcode breaks without doing anything

Hello,

I’ve got a problem with the shortcode and i can’t figure what happen.
I made the shortcode, put it in the page and it worked fine but after some time the shortcode is totally broken even if i don’t go in the settings of the plugin and i need to reconfigure all the options again.

My shortcode is :

[wordpress_file_upload uploadpath=”/uploads/manuscrits” fitmode=”responsive” uploadpatterns=”*.pdf, *.doc, *.docx” maxsize=”10″ duplicatespolicy=”maintain both” uniquepattern=”datetimestamp” placements=”userdata+userdata/selectbutton/uploadbutton/filename/progressbar/message” uploadtitle=”Envoyer des fichiers” selectbutton=”Sélectionner un fichier” uploadbutton=”Envoyer” successmessage=”Le fichier %filename% a bien été envoyé” warningmessage=”Le fichier %filename% a bien été envoyé, mais avec des avertissements” errormessage=”Le fichier %filename% n’a bien été envoyé” waitmessage=”le fichier %filename% est en cours d’envoi” requiredlabel=”*” notify=”true” notifyrecipients=”[email protected]” notifysubject=”Manuscrit envoyé depuis le site” notifymessage=”Bonjour,%n%%n%Un nouveau manuscrit a été envoyé depuis le site par :%n%%n%%userdata1% %userdata2%%n%%userdata3%%n%%n%Message :%n%%n%%userdata4%%n%%n%Retrouvez le fichier en pièce jointe de ce mail.%n%%n%Bonne journée,” attachfile=”true” successmessagecolor=””#ffffff”” successmessagecolors=””#ffffff,,#ffffff””” warningmessagecolors=””#dd9933,,#ffffff””” failmessagecolors=””#dd3333,,#ffffff””” waitmessagecolors=””#ffffff,,#ffffff””” widths=”filename:400px, userdata:200px” userdata=”true” userdatalabel=”Prénom|t:text|s:top|r:1|a:0|p:right|d:/Nom|t:text|s:top|r:1|a:0|p:right|d:/Email|t:email|s:top|r:1|a:0|v:1|p:right|d:|g:0″ userdatalabel2=”Parlez-nous de vous|t:multitext|s:top|r:1|p:right”]

But after a while it broke itself and changed to :

[wordpress_file_upload uploadpath=””/uploads/manuscrits”” fitmode=””responsive”” uploadpatterns=””*.pdf,” maxsize=””10″” duplicatespolicy=””maintain” uniquepattern=””datetimestamp”” placements=””userdata+userdata/selectbutton/uploadbutton/filename/progressbar/message”” uploadtitle=””Envoyer” selectbutton=””Sélectionner” uploadbutton=””Envoyer”” successmessage=””Le” warningmessage=””Le” errormessage=””Le” waitmessage=””le” requiredlabel=””*”” notify=””true”” notifyrecipients=””[email protected]”” notifysubject=””Manuscrit” notifymessage=””Bonjour,%n%%n%Un” attachfile=””true”” successmessagecolor=”””#ffffff””” successmessagecolors=”””#ffffff,,#ffffff”””” warningmessagecolors=”””#dd9933,,#ffffff”””” failmessagecolors=”””#dd3333,,#ffffff”””” waitmessagecolors=”””#ffffff,,#ffffff”””” widths=””filename:400px,” userdata=””true”” userdatalabel=””Prénom|t:text|s:top|r:1|a:0|p:right|d:/Nom|t:text|s:top|r:1|a:0|p:right|d:/Email|t:email|s:top|r:1|a:0|v:1|p:right|d:|g:0″”]

With lots of “” added everywhere in the shortcode and the options fields of the plugin.
Is there something wrong like a character i should not be using in the fields ?

Thank you

Marco
