ckeditor crashes(freezes) when copy-paste html code in source mode

[datahell]

I have to test it to answer you but I believe this is not the answer to your problem. The editor freezes because of what you copy-paste. Copy-paste plain text and I am sure the editor will not freeze. If the undefined "a" was the problem the editor would have the same problem even if you pasted a single character. BTW if I remember correctly "a" is from jQuery, not from the editor. If you pay attention to the source code of what you copy-paste you might get a clue why it freezes. The editor tries to represent whatever you paste to it. If you paste inaccessible data, blocked data, data with wrong html, etc, most probably you will create a problem similar to the one you have. It is like windows freeze some times when you try to open a, for example, inaccessible network drive.

We have already tried the size! No matter if the phrase that we copy (with ctrl+C and ctrl+V, NO right click) is small (e.g. /media/images/categories in the src of an image) or big (a full text with paragraphs), as soon as you leave the source mode to return to WYSIWYG, the ckeditor freezes. At that exact moment. And only for the translation! NOT the default language. The source freezes when you exit source mode, NOT when you enter.

As I said before, no matter what we paste, it freezes. Let's say we have a new location of an image and we want to update it for the greek, english and french article. We copy the correct image path from the greek and we want to paste to the translations. It freezes. We tried a dummy <p>This a paragraph</p>. The same. It has nothing to do with what it's pasted. The is the only thing I'm certain. And I said it from the beginning. Since you don't believe me, ask Nikos and Gerasimos. They both witnessed that.

We tried several staff since Thursday. Opera seems to have no problem, also Debian (with either Firefox or Chrome) have no problem. I have win 10 at home and tried new elxis at localhost. Now here, the problem occured only once, at the beginning, then it's ok. I have no problem.
I cannot figure that out any more...

I told you what you should look. I can't reproduce the problem. For me copy-paste works perfect even if I copy-paste text with images and CSS from the internet. Also I get 0 javascript errors in console window. My PC is old (windows vista) and it has not much ram but the copy-paste is super fast. The only thing I can do more for you is to connect to your pc with team viewer to see it. I have no other solution for you.

Note: If you connect to the internet via a proxy then this might be the problem (or an antivirus/firewall). I told you that similar problems are caused mostly by inaccessible data.

I think I understand what you thought! You think that the editor freezes when we paste sth. No... The editor freezes when you exit the source mode after you have pasted an html code for the translation only. When you hit the button source code to return to wysiwyg.

[datahell]

It is the same thing and makes stronger my belief that the editor freezes on rendering time (when you paste under standard mode, or you switch from html to standard mode) because it cannot render the content you paste. And this is not editors' problem! Other things blocks the editor from working. For me the cause of your problem is very clear. Case closed.

+1 to @datahell's thought. It's absolutely clear! Paste to a txt file what content try to be
rendered and send it back to us!

[Eleanna]

Since it so crystal clear to you that the problem is the html, explain to me why it does not happen to greek editor (which is the default language and there it is rendered fine), but it does happen to english and french.
I understand that it is a very "peculiar" issue, but, please, do not treat me like ....

@Eleanna,
Paste what you are trying to render from source code to wysiwyg in a txt file and attach it
for further investigation. Let's stop writing-talking with hypotheses.

I don't treat you like ... however i believe that we have spent so many hours to so obvious
issue.

PS: Greek language don't use latin characters.

Webgift I have already given you an example. It is the "/media/images/category/image.png". We replaced an image from the old site to a new location and we want to update the path to that image. So copy paste the url. Another example: We create a new article. We write whatever dummy in greek. We save. We go to translation and copy paste the "<p>This is a paragraph</p>" to source code. We do not try anything special. It is not sth specific that we paste.
I agree that we have already lost so many hours. I'm tired. And I don't want it to continue anymore...

I have followed the actions you've described and i can't find any issue. Can you give access
to your installation?

[Eleanna]

Unfortunately, I cannot give you access...
The only possible action is the team viewer Datahell suggested and he knows why this is the last and only action.
If you think that you want to get involved, tell me to send you pm with contact details.
Thank you for your time.

I don't use remote desktop sharing tools. Sorry.

[Eleanna]

I respect that. Thank you again for your time.
