WordPress PHP Dashboard Fix Errors

I need a skilled WordPress / PHP developer to clean up a handful of nagging issues on my main site, https://buysellcodes.co/. All of these features already work on our companion site, https://freelancerjobs.co/, so you will have a working reference when digging through the theme files, custom post types, and any plugin overrides.

Key fixes I’m after:

• “My Package → Add New” inside the user Dashboard no longer responds. The same module is fine on freelancerjobs.co, so the bug is likely theme- or plugin-specific rather than server-level. Trace the action hook / AJAX call and restore full create-package functionality.

• Within “Freelancer Options” and “Service Options,” numeric fields must accept decimals (e.g., 2.3 or 2.8) instead of forcing whole numbers only. A quick validation tweak or database field type adjustment should do it.

• The Proposal icon has vanished from the interface. Bring it back so it loads with the correct SVG / font-icon class and is fully clickable.

• Site messages are being routed to the wrong domain. Ensure all dashboard and notification links stay on buysellcodes.co and do not drift to freelancerjobs.co or anywhere else.

Please test everything end-to-end in staging first, then apply to production. Deliverables are updated PHP / JS files (or clear snippets for functions.php), any SQL changes if required, and a short changelog so I can keep the fixes under version control.
