I have a website where the civicrm plugin stopped working and developed an error. I have since copied the site onto another hosting account I have and have been following these upgrade steps (https://wiki.civicrm.org/confluence/display/CRMDOC/Upgrading+CiviCRM+for+WordPress#UpgradingCiviCRMforWordPress-verify_settings) to upgrade the plugin (as it's been a year and a half anyways). I've gotten to step 4 but when visiting the link it says
Sorry, you are not allowed to access this page.
I saw in the upgrade steps it mentioned if you have issues to activate the plugin in wp-admin/plugins.php but I've never done it that way. Is there a chance anyone can let me know if "activating" it via plugins.php file may work and how might I do that? If it isn't that (as I didn't deactivate the plugin before upgrade) why my Administrator account wouldn't have access to this page? of the civi crm dashboard in wordpress?
I had tried deactivating all the plugins via the wordpress backend but then I was shut out of my site (os there a way with this plugins.php file to activate them all again or do I have to delete and re-do all the steps again of getting another backup and upgrading civi crm?).
Thanks for your help!
