Hello again second time 🙂
I tried installing an old version 1.5.15, it works but database seems to be missing all tables from wp erp plugin, I noticed that the tables’ names are wp_erp_something (ex. wp_erp_hr_employees) but my db doesn’t contain any table that matches that even after installing and activating the plugin.
the plugin doesn’t work with full features, HR and Accounting modules’ pages give similar error:

HR Management

Thanks for your help

Thanks a lot for your support,
I checked that first of all, it didn’t work.
I also thought of creating the table myself, but i couldn’t find its structure.
would you please share that with me? and could it be of help to try to install a previous version?
