Clean reinstall on Wordpress

Question

New to CiviCRM. WordPress Version: 4.4.2 PHP Version: 5.5.32 MySQL Version: 5.1.73-log

I initially installed CiviCRM 4.6.14 LTS by mistake and rather than do an upgrade, I deactivated it, deleted it, and dropped all the tables from the database (It was installed to its own DB).

I neglected to remove the plugins/files directory or its contents, though.

I then installed 4.7.3 and when I activated it, I had green lights all the way on the installation page, so I just proceeded. However, any attempts to open CiviCRM resulted in errors (something about MySQL MyISAM).

So, I deactivated, deleted and then found that the db files were put in my Wordpress database, not the CiviCRM db. I deleted all those, and reinstalled 4.7.3.

Now, when I activate, I get a SQL Error -- table not found. Obviously, CiviCRM is still trying to use the WP database. I wholly expected to get the Install page again, but that never happened.

What setting is lurking around that uninstalling doesn't delete? How can I get a clean install that runs the installation check and lets me enter the alternate DB info. I tried https://MYSITE/wp-admin/options-general.php?page=civicrm-install, but all I get is "You do not have sufficient permissions to access this page.")

Thanks!

EDIT: Here's the error message I get when I try to activate civicrm: Initialization Error

Answer 1

Uninstalling CiviCRM doesn't delete its settings which are stored inside wp-content/uploads/civicrm folder. The best option is to delete that folder (it solves this issue in my case).

WARNING! Remember about making backups before deleting anything.

Answer 2

My advice would be instead of fixing the existing instance please try to install an fresh copy which will be easier

please refer to the following link for installation process https://wiki.civicrm.org/confluence/display/CRMDOC/WordPress+Installation+Guide+for+CiviCRM+4.5

---

If you want to fix the existing Installation then please look for civicrm.settings.php file

you can find the file against .../wp-content/plugins/civicrm/civicrm.settings.php

you can see CIVICRM_UF_DSN and CIVICRM_DSN this will say which DB is been linked make your changes also clear cache and try again it should work

thanks - I guess this helps!
