Omeka Classic Troubleshooting

Would like to use OMEKA.
But problem with Omeka_File_Derivative_Strategy_ExternalImageMagick

ImageMagick is running well on the server HostPapa

In the sample below for security I replace display of ACCOUNT and DOMAIN

Could someone help ?

Omeka 2.4.1
PHP 5.5.35 (cgi-fcgi)
OS Linux 2.6.18-502.el5.lve0.8.85 x86_64

Have you checked the ImageMagick Directory path in Settings on the admin side? If the default path that Omeka tries to guess, you might ask your hosting company what the correct path to ImageMagick should be.

Thank you for your feedback
Running the following scipt :

<?php echo "
";
system('which convert',$path); print_r($path); 
echo "
"; ?>

I got this output:

/usr/bin/convert
0

It seem that the path /usr/bin is OK ?

I solve this problem by changing to :

fileDerivatives.strategy = “Omeka_File_Derivative_Strategy_Imagick”

I presume that the extension ImageMagick is not on our Server, but extension Imagick is there !

Hope this distinction will help other people !

Thank you
