I have found two issues with the latest install of ISPConfig 3.1 and the upgrade to 3.1.15p3 when installing on CentOS 7.8.2003. I used the stable release for both the install as well as the upgrade. Missing column in database After the installation is completed I tried to add a new domain through the Web interface, which didn't work since the column fastcgi_php_version on table web_domain is reported missing. Going through the incremental SQL files folder I noticed that although column first is added through file upd_0031.sql, it is later removed through file upd_dev_collection.sql in this section: -- we have to decide whether to delete the column or leave it there for investigating not-converted entries -- ALTER TABLE `web_domain` DROP COLUMN `fastcgi_php_version`;Although the line is commented out in the file, it still gets executed on my system and thus being removed from the table. I had to manually add the column back to the table. File attributes error during upgrade When I executed the automatic upgrade using ispconfig_update.sh I get the following error: PHP Warning: fopen(/var/www/php-fcgi-scripts/ispconfig/.php-fcgi-starter): failed to open stream: Permission denied in /tmp/update_stable.sh.Yd2DZjizZ2/ispconfig3_install/install/lib/install.lib.php on line 466The reason for this is that the i flag is added to the file attribute during the installation, but the upgrade script does not remove the flag before attempting to read/modify it. I solved this by executing chattr -i on the file after the installation, but before running the upgrade script.
