Hello anybody can help with that problem on old cake app:
[Wed Sep 26 18:58:29.454771 2018] [core:crit] [pid 28046:tid 140483665811200] (13)Permission denied: [client 170.231.113.140:34906] AH00529: /home/vtecnet/public_html/admin/app/webroot/.htaccess pcfg_openfile: unable to check htaccess file, ensure it is readable and that '/home/vtecnet/public_html/admin/app/webroot/' is executable
In fact the error message is giving you all the information:
[…] ensure [.htaccess] is readable and that '/home/vtecnet/public_html/admin/app/webroot/' is executable
I don’t know which version of CakePHP an old cake app is, since you’re not telling us, but looking at file permissions and chmod should point you in the right direction.
WordPress has a nice article on permissions: https://book.cakephp.org/1.3/en/The-Manual/Developing-with-CakePHP/Installation-Preparation.html#permissions
Something like this could help you out, if you have shell access to the server:
# set the ownership to the webserver user (i. e. www-data)
chown -R <insert_webserver_user_here> /home/vtecnet/public_html/admin/
# set permissions recursively
chmod -R 755 /home/vtecnet/public_html/admin/
