I have run in this problem:
I am copying in article editor many lines of code with similar pattern like:
<p><span style="color: #3333ff;">One Two Three Four Five |83|</span><br/>
One Two Three Four Five </p>

<p><span style="color: #3333ff;">One Two Three Four Five |84|</span><br/>
One Two Three Four Five</p>


- I can save article with exactly 82 such fragments , but no more:(
I need 110 fragments like this and I am constantly getting 403 Error when trying to save and it doesn't save anything below the line......
I have tried several editors and even browsers, it's the same....
How to get my article in?

It seems it was some server security probably;
Host gave me a few lines of code to add to .htaccess and I was able to save item....
