After dealing with a corrupted wordpress site and reinstalling wordpress, i re-enabled the civicrm plugin but did not re-install civicrm.
The backend seems to work fine except that widgets do not work and the Civicrm Page needs to be recreated. I tried to re-save the Civicrm page in the CMS integration admin form. Also tried to run the installer /wp-admin/options-general.php?page=civicrm-install but get a message: You do not have sufficient permissions to access this page.
I suppose I could disable the civicrm plugin, wipe the database, install civicrm and overwrite the database but wondering if there is a more practical solution?
