[Resolved] Error: "Incompatible Archive" uploading Zip file

Hi,

I've tried it on my localhost - these are the results:

ArchiveOld.zip - it worked (I got The uploaded xliff file doesn't belong to this system, as expected)
ArchiveNew.zip - I also got "Incompatible Archive

But then I did the following - extracted the files from ArchiveNew.zip and created a new zip archive (I am using Kubuntu Linux OS, which uses Ark KDE Archiving tool). After that I tried to upload it and got "The uploaded xliff file doesn't belong to this system", meaning that it would most likely work. So the solution might be very simple hopefully - simply extract files and create an archive anew. It might help :).

Hi,

WPML is generating the message "Incompatible Archive", so can you tell me what checks WPML do?

Please see this answer:
https://wpml.org/forums/topic/can-not-import-translated-xliff-not-a-valid-xliff-file/#post-2475163

George is our 3rd tier support and he said this in that reply: "Yes, WPML uses the temporary folder that PHP uses to read and generate the appropriate xliff files. You can take a look at the method import_xliff() in /wpml-translation-management/classes/xliff/class-wpml-tm-xliff-frontend.php"

Here is a chunk of code from there with our error message:

  
		if ( class_exists( 'ZipArchive' ) ) {
					$z     = new ZipArchive();
					$zopen = $z->open( $file['tmp_name'], 4 );
					if ( true !== $zopen ) {
						$this->error = new WP_Error( 'incompatible_archive', __( 'Incompatible Archive.', 'wpml-translation-management' ) );

						return false;
					}
					$empty_files = array();
					for ( $i = 0; $i < $z->numFiles; $i ++ ) {
						if ( ! $info = $z->statIndex( $i ) ) {
							$this->error = new WP_Error( 'stat_failed', __( 'Could not retrieve file from archive.', 'wpml-translation-management' ) );

							return false;
						}
						$content = $z->getFromIndex( $i );
						if ( false === (bool) $content ) {
							$empty_files[] = $info['name'];
						}
						$contents[ $info['name'] ] = $content;
					}
					if ( $empty_files ) {
						$this->error = new WP_Error( 'extract_failed', __( 'The archive contains one or more empty files.', 'wpml-translation-management' ), $empty_files );

						return false;
					}
				} else {
					require_once ABSPATH . 'wp-admin/includes/class-pclzip.php';
					$archive = new PclZip( $file['tmp_name'] );
					// Is the archive valid?
					$archive_files = $archive->extract( PCLZIP_OPT_EXTRACT_AS_STRING );
					if ( false == $archive_files ) {
						$this->error = new WP_Error( 'incompatible_archive', __( 'You are trying to import an incompatible Archive.', 'wpml-translation-management' ), $archive->errorInfo( true ) );

						return false;
					}

According do this:

 require_once ABSPATH . 'wp-admin/includes/class-pclzip.php'; 

It would seem that WordPress core function is also included in this, so the issue might be with the zip alone, something went wrong there and recreating it anew would fix it.

Hopefully this will shed some light of this, not sure what else to add here.

Hi,

Possible there are some issues with the ZIP generator on the client site (Translators).

That would be the only explanation for this, I have no idea what else could it be indeed.
