I just did an update from 1.0.2 to 1.0.3 on my local installation (Windows 7, Apache 2.2.11, PHP 5.3.1), and had a problem at first with TinyMCE (also with the "legacy 1.0 template", to be posted separately).
Update method was to copy my config.inc.php and custom files from assets folder into a freshly unzipped 1.0.3 set of files and run the update on the existing database, with selective set of snippet etc. installs/updates.
I’m pretty certain I had selected the new TinyMCE for installation, but when I tried a page of my site that uses RTE, I got error messages referring to missing files in a tinymce3241 folder. Looked in Manage Elements > Plugins and found no new TinyMCE installed. I hadn’t deleted the installer, so ran again with just TinyMCE selected. It was then installed OK.
I use TinyMCE on the front end, so once again had to fish about in the older version’s Plugin > TinyMCE > Configuration to get it showing with the toolbars, styles etc. I want. Is it possible to include custom configurations from there in the upgrade actions?
