Hi Melissa,
WB works also in PHP 5.6.x and PHP 7 (actual beta 7.0.0.RC7)
for the FCKeditor... some users reported problems with the FCK together with the Internet Explorer 11 (newer not testet). It works for me, if i add my used Adress into the list for the compatible mode in IE11 (see IE11-settings)
for WB, you have to know, that WB use the Charset UTF8 since WB 2.8.3 SP4 as Standard Charset, so if you dont use the same charset in your working WB, its possible, that some entrys needs a correction (text-fields in page-settings for keywords and description, text-fields in WB-Settings etc)
i recommend a test with the latest wb-package, maybe in a subfolder of you installation with the same database
if interest,
- download the latest package
from here and unpack the files in a empty locale folder
- download the lastest SP5-Test
from here and unpack the files in the same locale folder - be sure, that you overwrite all existed files
- delete the folders
install and
pages and also the files
config.php and
upgrade-script.php- copy the folder
pages from your working WB into the the folder with the new WB-Version
- copy the
config.php from your working WB into the folder with the new WB-Version
- add in your working WB a new subfolder, called "wbtest" or whatever you want
- change the WB_URL in the copied
config.php of the new wb-test-package, add there the foldername from your testfolder on the right place, example:
working WB-Adress:
http://yourdomain.comfoldername of the test folder: wbtest
new WB_URL in config.php of the test package:
http://yourdomain.com/wbtestnow copy all the files from your locale folder into the new added wbtest-folder on the server.
to make this job faster, build a zip from the complete package in your locale folder, upload this to the online test folder and use a standard unzip file in the attachement to unpack the package (select the WB-Package-zip and click on the unzip-button, if the script is finish, it sends a succsess-message, delete the unzip.php, if you are finish)
for a standard wb-package it needs maybe 20-30 sec to unpack the zip, a backup-zip from a bigger project (over 100 mb incl. media files) needs a little bit more
the forum here accept only zip-files, so its needed to unzip the unzip.php first

to test all this, called in the browser with the new WB_URL.
Avoid to make changes in the content of the test-WB, because it use the database of the working wb
but its needed for a test to enable the PHP-Error Messages in the WB-Settings -> Advanced Settings
Use there a Setting with E_ALL (recommend E_ALL && E_STRICT) - dont forget to set the PHP-Error Messages to E_NONE after the test
test btw visit all your pages in front- and backend.
If you found error messages, copy this message into a text file - we need then the module version of the used module, if its not a module, delivired with the WB-Package
P.S.1: if you need help, ask for it
P.S.2: i've some WB 2.8.1 and WB 2.8.2 under PHP 5.6.3 and 5.6.15, running without problems in the frontend. in one of the installations i use a old version of the gmap-module. its shows the selected map in the frontend, but its not possible to edit something in the backend
P.S.3: some users recommend a new install for a test in a sub-folder of the running server, but a new install build also new tables in the database with the new settings for database collation etc. A test like this shows not the same result like a upgrade from a working wb, thats way i recommend a test with the actual database
