If you instead installed a stack (like Bitnami WordPress stack), or a module for LAMP (like Bitnami WordPress module), you will instead need to modify /opt/bitnami/apps/wordpress/conf/htaccess.conf.
However, you mentioned using a Bitnami LAMP. We assume you run the app files under /opt/bitnami/apache2/htdocs. If so, the
.htaccess files should work.
If they do not, we have a Support Tool that will gather relevant information for us to analyze your configuration. Could you please download and execute it on the machine where the stack is running by following the steps described in the guide below?
How to Run the Bitnami Support Tool
Please note that you need to paste the code outputted by the tool in your reply.
