HELP: Fatal error: Cannot redeclare class FormHelper
I am trying to install Concrete5 22.214.171.124. on my webhotell. When i am in the direcory for Concrete, i cant get to the installation page, but i get this message:
Fatal error: Cannot redeclare class FormHelper in /home/*mydirectory*/public_html/concrete/concrete/helpers/form.php on line 20
in the case of upgrading try the following:
- Upload a new core (/concrete folder) to your site, this can be the exact same version you are running now.
- add /tools/upgrade?force=1 or /index.php/tools/upgrade?force=1 behind your domain name (in the browser you use, not in the site.php) to run an "upgrade".
if you upload the same /concrete as the version you are running it still "upgrades" to that version.
Doing this results in fixing any missing files and database pieces.
In the case of a fresh install, remove all files/folders. download a new concrete5 version and upload it.
