Hello, I am writing because I downloaded the trial version of the program "Arrowchat", but I have big problems to install it, I will explain the problem:

I have to add this line to the file. Htacces to be able to install Arrowchat,

RewriteCond% {REQUEST_URI}! / Arrow /

But there is a problem when I add this line, the site no longer works, so it is impossible for me to go to the page ... my-website/arrow / install if I do not add this line RewriteCond% {REQUEST_URI} ! / arrow / file. htacees

What should I do?

best regards
