Hi,
One of our client facing issue with "Error creating thumbnail: sh: /usr/bin/convert: No such file or directory Error code: 127"
"/usr/bin/convert" file not available on server. For this issue install imagemagick on server.
Simply you can run below command on server. It will install imagemagick on server.
Quote/scripts/installimagemagick
you can confirm imagemagic path by using below command.
Quotewhich convert
Above command will show imagemagick path that is "/usr/bin/convert".
That's all :)
