Yiwuku has shared it before Zblog PHP theme and plug-in installation method For some websites that cannot directly upload and install zba or gzba files in the background, or even prompt that the upload is successful without reporting an error, but not in the application list, today we will summarize the possible reasons.
The first possibility: there is a problem with the theme or plug-in package itself
In some cases, the zba file package downloaded by non-standard browser or P2P download software may be modified. At this time, the installer will be unable to parse the zba file, resulting in upload failure. In this case, it is usually recommended to use standard browsers such as Firefox or Google Chrome to download the file package.
The second possibility: the size of the zba file package exceeds the upload limit
The upload size of PHP environment files on many website servers is limited to 2MB. Files beyond this size cannot be uploaded online. If you have permission to configure the website environment, we can find the upload_max_filesize parameter in the php.ini file in the directory where the PHP program is located, and change 2M to a larger value, as long as it is not greater than the post_max_size parameter value. If you are using a virtual host and the management panel does not have the permission to modify the upload_max_filesize parameter, you need to contact the customer service of the space provider for processing.
The third possibility: insufficient permissions of website related directories
Under normal circumstances, the Z-BlogPHP installer will detect and prompt that the zb_users folder and subfolders need write permissions. If you do not pay attention during installation, you need to check the permissions in the server or FTP. Without write permissions, you cannot install themes and plug-ins online. Windows users can directly remove the read-only attribute of the zb_users folder and apply it to subfolders. It is recommended to set it in IIS; Linux users can directly give 777 the highest authority, or even 755 the authority.
At present, the user feedback on problems encountered by Yiwuku is about these three situations. In addition, there is a rare extreme case where there is no upload and submit box above the theme and plug-in management list. At this time, you need to check whether the plug-in in the "Application Center" is running normally and whether the plug-in is not enabled or has other exceptions.
