So, to continue:
I found this line in my file (line 2)
<?php require_once("WA_iRite/WARichEditorPHP.php"); ?>
and manually changed it to
<?php require_once("HTMLEditor/WARichEditorPHP.php"); ?>
Tested again and it worked fine.
On my local machine I tested the things that I'd had problems with and all worked fine.
I then uploaded to my testing server http://langerweb.com/untitled.php and found two problems.
Inserting an image:
Clicking on browse server I get an image showing which I can edit in all sorts of marvellous ways. On my localhost I just double clicked the image I wanted to insert and it worked fine. Double clicking on my remote server however does not insert the image. Perhaps I'm being a bit dense but how to you actually insert the image onto the page?
Then I tried that old chestnut of the table cells. Again in FireFox all is fine but in IE8 it still exists (for me) that if I right click in a cell I get a menu flyout but if I then hover on one of the choices I do not get another flyout.
However, I found that if I double clicked on a choice the second menu does appear. As far as I'm concerned that's case closed on that one. I'm sure that it's specific to me and my PC and that it will only affect a very few people. It's just a question of saying to them "Double click it".
So far this is all I've found.
