inux mint php由7.4升級至8.3後，網站不能進入頁面，解決方法﹕

將所有php版本除去﹕

sudo apt purge php*.*
sudo apt autoremove -y

重裝php7.4
sudo apt install php7.4
sudo apt install -y php libapache2-mod-php php-mysql

重啟apache2
sudo service apache2 restart

若不能進入網頁，出現Error: Class 'DOMDocument'not found 於filter_dom_load()
是因為伺服器缺少PHP的DOM擴充套件(extension)

若在Apache/Nginx使用
sudo apt-get update
sudo apt-get install php7.4-xml
sudo service apache2 restart
sude servic php7.4-fpm restart

大功告成﹗

瞬眼間一年又過去了，每年九月下旬都要更新PositiveSSL，寫下更新步驟作記錄

1. 購入認證

2. 在伺服器中產生CSR

3. 上載CSR到認證發出機構

4. 加入CNAME記錄，確認身份
用下以步驟，編輯CNAME記錄﹕
a. 進入Namecheap賬戶
b. 在表列選單中選取Domain List，按Manage按鈕
c. 按Advanced DNS去溜灠Host Records
d. 選取CNAME Record同時輸入正確目的值，再按Save All Changes按鈕

完成後強制認證﹕
Dashboard > 'SSL Certificates' > Click 'Details' near the certificate in question > click on "from this page (Edit methods)" (in the yellow box) > click on the drop-button "Edit Methods" itself > click "Save Changes/Retry Alt DCV”

手動昇級phpMyAdmin

1. 備份phpMyAdmin
sudo mv /usr/share/phpmyadmin/ /usr/share/phpmyadmin.bak

2. 創建新phpMyAdmin資料夾
sudo mkdir /usr/share/phpmyadmin
cd /usr/share/phpmyadmin/

將相集上載至﹕
drupal_path/sites/defulat/files/my_galleries

將相集加入www-data群組內﹕
sudo chgrp www-data -R photo_album

將相集設定使用者及www-data
sudo chown -R user:www-data photo_album

將相集設定為權限為770
sudo chmod -R 770 photo_album

用Brilliant Gallery 在文章中加入相集

依據提示修改﹕
sudo nano /usr/share/phpmyadmin/libraries/common.inc.php

使Function get_magic_quotes_gpc()不生效

/*
Function get_magic_quotes_gpc()
...
*/

然後重啟apache2

sudo systemctl restart apache2
