exist WordPress in the security configuration of thewp-config.php It is not uncommon to see two easily confused constants:

disallow_file_edit
DISALLOW_FILE_MODS

The names are similar, butCompletely different scope of action, level of risk control, and application scenariosIf you choose the wrong one, it will affect your daily operation and maintenance. If you choose the wrong one, it will affect the daily operation and maintenance, or directly block the backend update ability. This article will start fromFunctional differences, underlying behavior, practical usage scenariosThree levels that speak to how to choose the right one.

I. What does DISALLOW_FILE_EDIT do?

define('DISALLOW_FILE_EDIT', true);

1. What does it specifically prohibit?

This constantJust one thing.::

Disable the File Editor in the WordPress Backend

Included:

Appearance → Theme File Editor
Plugins → Plugin File Editor

When enabled, these two portals will simply disappear.

2. What does it not prohibit?

This is something that many people tend to misunderstand:

able to Install / Remove / Update Plugins
able to Install / Remove / Update Themes
Does not affect automatic updates
Does not affect WP-CLI
No impact on FTP / SSH / panel operation

Essentially, it just doesn't let you inChange PHP files directly in the backendThe

3. What is the appropriate scenario?

take precautionsMisuse to change bad code
Prevent low-privilege accounts from using the backend editor to plant malicious code
Still want the backend to update plugins and themes properly

👉 This is a "low-risk, cost-effective" basic security program.

What does DISALLOW_FILE_MODS do?

define('DISALLOW_FILE_MODS', true);

1. It has a very wide range of control

This constant will directly disable the All document-level change behaviors, included:

❌ Install plug-ins
❌ Update plugin
❌ Delete plug-in
❌ Install Theme
❌ Update Theme
❌ Delete Topic
❌ Edit theme/plugin files in the backend

In other words:

backstage from now onNo more writes to the file system

2. It affects more than just the UI

A lot of people think it's just "the background buttons don't work", but it is:

WordPress auto-update will not work
Some plugins that rely on self-updating report errors
Requires FTP / SSH / CI to do any updates
Significantly higher requirements for O&M processes

It's aLevels of "locked system" biasThe

III. Comparison of the core differences between the two

comparison term	disallow_file_edit	DISALLOW_FILE_MODS
Disable background editing PHP	✅	✅
Prohibit installation of plug-ins	❌	✅
Disable plug-in updates	❌	✅
Disable theme installation	❌	✅
Impact on automatic updates	❌	✅
Risk control level	center	your (honorific)
O&M complexity	lower (one's head)	your (honorific)

One sentence summary:

EDIT = disable "code change"
MODS = Ban "All Modifications"

Fourth, how to choose more appropriate? According to the real use of the scene to

Scenario 1: Personal Site / Content Site / General WooCommerce

Recommended Configuration:

define('DISALLOW_FILE_EDIT', true);

The reason is straightforward:

Avoid mistakenly changing the code in the background
No impact on plugin updates and routine maintenance
Lowest O&M costs

this isOptimal solution for most sitesThe

Scenario 2: Business Site / Multi-Person Collaboration / Client Site

Recommended Configuration:

define('DISALLOW_FILE_EDIT', true);

Match:

Strict user rights management
Code modification via Git / FTP only

Unless you already have a complete deployment process in place, theNot recommended to go straight on DISALLOW_FILE_MODSThe

Scenario 3: Enterprise / High Security / Code Freeze Environment

Only then consider:

define('DISALLOW_FILE_MODS', true);

Applicable:

Yes CI/CD
All plugin themes are managed by the code repository
Do not allow any "temporary operations" in the background.

this isOps-oriented configurations, not novice safety switchesThe

V. Can you use both together?

Yes, but be clear about the consequences:

define('DISALLOW_FILE_EDIT', true);define('DISALLOW_FILE_MODS', true);

The effect is equivalent:

The backend is completely "read-only".

If you just want to prevent messing with the code.use (sth) on its own disallow_file_edit That's enough.The

VI. Practical recommendations

✅ Sites for 90%: use only disallow_file_edit
⚠️ DISALLOW_FILE_MODS It's not "safer", it's "more closed".
❌ Don't just activate it to "look professional". DISALLOW_FILE_MODS
🔒 Security ≠ more restrictions are better, but ratherReasonableness of control points
