Solutions to some common problems during WordPress migration, WordPress migration

1. Importing database prompts that the data table already exists

Take the hosting provider used by Zhou Liang's blog - Host 91 as an example. It provides the phpMyAdmin function. To import the database, you only need to conveniently select the database and import it. Although the method is simple, you may encounter the prompt database XXX table has existed. The reason for this problem may be that after uploading the website files to the host space during the previous transfer, a website installation was performed, which resulted in the creation of a new database and new data tables, resulting in duplicate data tables when the database was re-imported. The solution is to find the existing XXX table prompted, delete it and then re-import it.

2. After the website files and data are uploaded successfully, the layout is disordered

First of all, we need to check whether the PHP version of the website is set correctly. For WordPress, PHP version 5.3 or 5.4 is generally used. If it is 5.2, it may cause confusion in the layout of the website. Take the host 91 used by Zhou Liang's blog as an example. Log in to the control panel and change the select php version to version 5.3.

If the modified PHP version still cannot take effect, then we need to check whether the loading file path of the website to load the website file is correct. Right-click the browser-inspect element to check the loading status of the website. You may find that many files are not loaded. If you look at the access path, you will find that the website access path and the website file loading path are inconsistent, so we need to connect to In the database of the website, modify the path for loading the website data file in the options table in the database to be consistent with the website access path.

3. Visit the blank homepage

Log in to the WordPress backend, go to Appearance - Theme and check whether the corresponding theme has been uploaded before migrating the website. If the previous theme is not found, you need to re-add the theme or re-upload the theme in wp-content/themes in the control panel, and then enable the theme in the WordPress background theme management.

4. Some functions on the website cannot be used

Log in to the WordPress backend, go to Plug-in Management - Installed Plug-ins, check whether all website plug-ins have been enabled, and enable the plug-ins corresponding to the website functions.

5. The homepage of the website is accessible. Clicking on other options does not respond or prompts a 404 error

Log in to the hosting space control panel, open View Hidden Files in the File Management section, and check whether .htaccess has the correct content. The content of the generally initialized .htaccess file is:

<p># BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /WP/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /WP/index.php [L]
</IfModule></p><p># END WordPress</p>

If there are redirects or static links set up, the same content as the previous website must be added.

PS: Recommended plug-in backup method
WordPress Move is a very good website backup and restoration plug-in, which supports one-click complete backup of all files and databases of the entire website, and one-click restoration; it can also send backup files to other host spaces through FTP to realize website relocation. The backup packaging of this plug-in is very smart, and each compressed package can be decompressed independently.

After enabling the plug-in, in Settings > WordPress Move, set the FTP information of the remote backup host, and the maximum size of each database package and file package.

Then visit Tools > Backup Manager to back up. You can back up the database individually or the entire site. The backed up files will be saved in the backup directory under the plug-in, so before backing up, please make sure your host has enough space to store the backup files

After backing up, visit Tools > Migration Assistant, there are 3 functions available:

Change domain name - you can change the domain name of the current website and it will replace the old domain name in the database in batches;

Migration - You can send your backed up files and databases to the remote host space (that is, the FTP set above). Before using this function, please install WordPress and WordPress Move on the remote host space, and then The above FTP remote backup path is set to the backup directory under the plug-in. In this way, after the backup file is sent, you can access WordPress Move in the remote host space and restore it through the "Restore" function, thus realizing the website relocation.

Restore - You can select backed up files from the backup directory to restore.

Search WordPress Move in the background plug-in installation interface to install it online
