[AITpro Admin]

Email Question:

Hey Edward, hope all is well with you.

I am setting up my email plugin and now I have a 403 error trying to see the content at this page:

Answer:

What is being blocked is the html file in the WP /uploads folder by the BPS Pro UAEG htaccess file: /wp-content/uploads/mailster/templates/mailster/index.html

https://forum.ait-pro.com/forums/topic/uploads-anti-exploit-guard-uaeg-read-me-first/

Do these steps to create a whitelist rule for the /uploads/mailster folder:

To edit/customize your Uploads Anti-Exploit Guard (UAEG) .htaccess file go to the B-Core > htaccess File Editor tab page > “Your Current Uploads htaccess File” tab and do the steps below.
1. Copy and paste your entire Uploads .htaccess file code from the “Your Current Uploads htaccess File” tab on the htaccess File Editor page into the CUSTOM CODE UAEG text box on the BPS Custom Code tab page.
2. Edit/modify/customize your UAEG htaccess code in the CUSTOM CODE UAEG text box on the BPS Custom Code tab page.
3. Click the Save UAEG Custom Code button to save your UAEG custom code.
4. Go to the Security Modes page and click the UAEG BulletProof Mode Activate button.

You have an Apache server so this is the whitelist edit that you need to do in the UAEG htaccess code in the CUSTOM CODE UAEG text box:

To whitelist a folder: Remove/delete the # sign from infront of this line of code in your UAEG htaccess code and change the folder name to your actual folder name that you want to whitelist.
SetEnvIf Request_URI “mailster/.*$” whitelist

Delete the # signs in front of #Require env whitelist and #Allow from env=whitelist shown highlighted in yellow below in your UAEG code that you copied to CUSTOM CODE UAEG.

# FORBID THESE FILE EXTENSIONS FROM BEING ACCESSED OR EXECUTED REMOTELY

A different Mailster issue. If you see wp-admin 403 errors like this one below. Do these steps to fix the issue:

1. Copy the modified wp-admin Query String exploits code below into this BPS wp-admin Custom Code text box: 4. CUSTOM CODE BPSQSE-check BPS QUERY STRING EXPLOITS AND FILTERS.
2. Click the Save wp-admin Custom Code button.
3. Go to the BPS Setup Wizard page and run the Setup Wizards.

# BEGIN BPSQSE-check BPS QUERY STRING EXPLOITS AND FILTERS
# WORDPRESS WILL BREAK IF ALL THE BPSQSE FILTERS ARE DELETED
# Use BPS wp-admin Custom Code to modify/edit/change this code and to save it permanently.
