EDIT: I rephrased the question because I have not explained well. Let’s see if this time we do best.

I’m working on a very simple blog system in PHP and MySQL through Kohana Framework. For the content of a post / entry I am using TinyMCE (POST request). I recently tried to add an entry with a piece of code in javascript by way of explanation, but it is running a part of it. More specifically I’m “using” the “exec()” inside TinyMCE/textarea (not to run it). Something like:

/regexval/.exec('string');

As I say, the problem is in the call to “exec” and when I send the form Kohana returns me the following message:

TTP_Exception_404 [ 404 ]: Unable to find a route to match the URI: 500.shtm

It seems that there is an internal error which I do not know where. My CPanel error log not showing anything and on localhost it’s working properly. I wonder if there is a time when this function can be executed. I tried to debug in stopping Kohana during request execution, but whenever I stop the execution “$_POST” is empty, so I guess the problem is elsewhere.

I suppose it’s a rookie mistake, but I do not know what can be and have not found anything about it (maybe I have not looked properly). So if someone can shed some light, I would be grateful. And if it is necessary to provide other information, please let me know.

Thanks for your trouble and sorry for my english.

    After trying without success to detect the problem, I chose to contact the hosting. Apparently is due to a rule of “mod_security” module installed on the server. One solution, if you don’t want or can’t disable this rule is to change the text in some way, for example, adding spaces between letters:

    /regexval/.e x e c('string');

    Sorry for wasting your time, maybe I should first ask my hosting, but first I had not thought of this possibility. I have also removed the pasted code because they take place and ultimately not necessary.

    Thanks for your time.

    EDIT:

    cs278, from kohana forums, proposes another solution (in this case functional):

    RegExp.prototype['ex'+'ec'].call(/regexval/, 'string');

    Best regards.
