If you installed InvoicePlane in a subdirectory of Wordpress just leave the Wordpress .htaccess unchanged and replace RewriteBase / with RewriteBase /invoiceplane-directory in the .htaccess file in the InvoicePlane folder.
Thanks Kovah. Where does one enter their database login information (I put it in invoiceplane/application/config/database.php), and do the initial table creation? I’m getting this:
A Database Error Occurred
Error Number: 1146Table 'iplane.ip_settings' doesn't existSELECT *
FROM (`ip_settings`)Filename: $PATH/invoiceplane/modules/settings/models/mdl_settings.phpLine Number: 59
Perhaps also worth noting, from the local file system, there is no /modules/ in invoiceplane/
