Hello,
In most recent release we dropped the Apps/StaticPage module. Outdated code in that module caused the first error and from there, some other code didn't execute properly and the upgrade process did not finish successfully.
The simplest way would be right now to either restore the backup you probably made before the upgrade, fix the error (as described below) and go through upgrade process again. If you don't have a backup to use, you can try to change the version of epesi in database - in table "variables", row with name="version", change value to:
s:5:"1.1.5"
then fix the error and re-apply update.
To fix the initial error, please either uninstall the module (using the /admin panel) or edit file modules/Apps/StaticPage/StaticPageInstall.php, find the line
array('name'=>'Libs/FCKeditor','version'=>0),
and replace with
array('name'=>'Libs/CKEditor','version'=>0),
And in modules/Apps/StaticPage/StaticPage_0.php replace
$fck = & $f->addElement('fckeditor', 'content', $this->t('Content'));
with
$fck = & $f->addElement('fckeditor', 'content', $this->t('Content'));
I apologize for inconvenience caused.
Kind regards,
Arek
