MetaSlider Pro Installation Troubleshooting

This guide has some recommended steps to follow if you encounter problems installing MetaSlider Pro.


“The package could not be installed. PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature”

If you see this error message, please check you are uploading the correct file. The “ml-slider-pro” file should be a .zip file (not a .php file).

The most common reason this happens is because Safari has been used to download the plugin. Safari automatically unzips files after they’ve been downloaded. Please try using a different browser to download the plugin zip file.

Do not unzip the ml-slider-pro.zip file before installing it on your WordPress site.


“Unable to create directory content/uploads/XXXX/XX. Is its parent directory writable by the server?”

This error indicates you have a permissions problem with your WordPress installation. Every file and every folder on your server have permissions defined that indicate who can create directories, create files, delete files and so on. This error indicates the permissions on your content folder are too strict, and need to be relaxed in order to let WordPress create directories.

You will need to update the permissions on the content folder and set them to 755. There are 2 ways to do this:

cPanel

  • Log into your hosting cPanel
  • Go to the File Manager
  • Select ‘Web Root’ as the Directory to open
  • Right click on the ‘content’ folder and select ‘Change Permissions’
  • Change the permissions to “7 5 5”.

FTP

  • Using an FTP Client (FileZilla recommended), log in to your server using the details your host provided.
  • Navigate to the ‘public_html’ folder.
  • Right click on the ‘content’ folder and select ‘File permissions…’
  • Change the permissions to “755”
