How to work in Joomla?

Question

Joomla

Guys such a question. I work in SEO. The thing is, I need to make improvements to the site. Site on Joomla 1.5.22
There you need to change the titles, some links, images, logos, and so on.
As far as I understand, I need access to the database?
It seems like they write that the main info is stored in the database.
I looked at both FTP and Admin. Didn't find anything. The client is harmful, does not want to give access to the database.
Tell me, please, maybe I'm not looking there.
Thank you!

Answer 1

Well, then fuck him.
Make a list of changes that are needed for optimization.
Let the developer do it.
On the topic, you don’t need a database, everything is in the admin panel.

Answer 2

0) Joomla 1.5 is a leaky sieve
1) Managed through the admin panel (the question is whether full access to the admin panel)
2) there is a configuration file with access to the database on ftp
3) having access to the database, you will have to understand the structure and connections of the CMS before you make at least one fix.
