Posted March 22, 20196 yr After upgrading to latest version of ipb, it runs only admin login, but admin and forum are empty pages. I've checked ips4.php, and got an error: Some or all of the columns in your database are not using the utf8_unicode_ci collation (ibf_blog_headers.header_image is utf8_general_ci). Trying to convert base, but it gives an error Error: Unknown column 'blog_view_level' in 'ibf_blog_blogs' File: /system/Db/Db.php Line: 198 In DB, there is no such a column: blog_view_level no clue what to do next..

March 22, 20196 yr ibf_blog_headers is irrelevant and can be dropped - it was a 3.x table not used in 4.x. There is no blog_view_level column in ibf_blog_blogs, so I'm not sure why the utf8 converter would attempt to it off hand, except maybe the x_utf_* tables still being present and having cached table information from prior to your upgrade to 4.4. Are you using PHP 7.1+? Have you checked your PHP and webserver error logs to determine if any errors are being registered? I don't think the original issue you referenced is UTF8-conversion related.
March 22, 20196 yr Author I've upgraded to PHP 7.2 with all required exenstions before upgrading forum. Wordpress is working without any problems on the same server. Edited March 22, 20196 yr by olegm
March 24, 20196 yr Author The problem was not in converting, but in Nginx (fastcgi) cache. Everything is fine and working now.
