Insufficient privileges

Hello,

I posted a new message on an old topic of mine because of a new issue and now after posting it explains me that i have insufficient privileges and that i can t even view my topic any longer ?
I could view my topic, i posted it, i viewed it many Times, i replied to it and now it doesn t exist to me any longer ? Why ?

Thanking you in advance

Ps: i use a smart phone not a pc.

If it can help i tried to edit the original post just before the topic disappearance.

Is this the topic you are referring to?  http://www.thecatsite.com/t/282458/making-cat-stay-indoor-im-hopeless-really#post_3597060.  It was held so that we could combine the multiple posts into one post.

Yes it's this topic. Thank you for your reply.
