    Posted: 27 January 2017 at 5:57pm
Chrome just released an update that appears to be broken or not work with WWF Rich Text Editor. I can reproduce the issue both on my own forum and on this, the official WWF support forum.

It appears that Chrome is adding an upside down L to the text area of the rich text message box. The issue is also occurring on the new version of Firefox (PC for sure, not sure on Mac). Internet Explorer injects a blank space.

Here is a screenshot of what is happening:

Steps to reproduce:

1) Log on to WWF using latest version of Chrome (Version 56.0.2924.76)
2) Create a new topic
3) upside down L is added to Message box

Personally, our staff freaked out a little about this. We were initially concerned that our site was hacked. However, as the issue appears to be present on this forum as well...it appears to be a browser bug or incompatibility with WWF.

Besides waiting for a Chrome update (likely 3 weeks away), is there an immediate fix in the source code?

The issue that causes this has been found.

From Firefox 17 the cursor did not display in the text area when typing in the Rich Text Editor. To fix this so the cursor displayed a ASCII Start of Text (Chr 2) was injected in to the Rich Text Editor.

This fix has worked for many years but is now causing strange effects in Chrome.

The issue is being looked in to and it looks at present that injecting a ASCII Delete (Chr 127) should fix the issue, but more tests will need to be done to ensure that it will work as a fix.

To try the fix yourself edit line 251 of RTE_textarea.asp and change it to the line below;


Response.Write(Chr(127))

I am using an old version of WWF, I found the following in root/RTE_textarea.asp:

'Firefox 17 fix, add space to allow carrot to display
If RTEenabled = "Gecko" AND strMessage = "" Then 
	Response.Write(Chr(2))
'Else display message
Else
	Response.Write(strMessage)
End If

I commented out the following line:

Response.Write(Chr(2))

The upside down L no longer appears in the textarea in Chrome/Firefox and the cursor appears to work as expected.

At appears you have not rolled out a fix to this forum yet as I am still experiencing the issue when I went to compose this response.

Thanks for the response on this. My issue is now resolved.

Cheers!

With Firefox you will notice that there is no cursor when you click on the RTE area. The cursor only appears once you start typing.

This causes some people to think that they cannot type in the RTE area when they click on it.

The fix places a hidden characters in to the RTE Area so when you click on it in Firefox the cursor appears so you know you can begin typing.
