I have 2 tikis working on different servers, with same configuration, themes, etc, and 3 wikipages that have the same code are not shown in one of them (all the menus, buttons etc are shown normally, but no text). The rest of the pages are shown normally on both servers.
As the problematic pages were quite big (or had big tables), I though it had to be memory related, but
- On server 1 with tiki 9.0 and php memory_limit = 256M pages are shown normally
- On server 2 with tiki 9.0 and php memory_limit = 256M pages are NOT shown (I have increased php memory to 516M and updated to 9.1, without results).
The blank page appears immediately (not a timeout related issue?)
Pages can be edited normally (not a Database related issue?)
Pages do not have many images, videos or attached files.
I have changed the server API from CGI/FastCGI to Apache 2.0 Handler (to make both servers equal)
What alse can cause the error?
How can I look for it?
Have you encountered similar situations?
I have compared the results of tiki-check.php and tiki-phpinfo.php for both servers, and look quite similar to me (except for innodb_additional_mem_pool_size and innodb_buffer_pool_size, but I think my problem is not related to the database)
I have activated PHP error messages, but get the same error messages from pages that load normally than on the 3 problematic pages.
I have searched around the forums and documentation, but most of the times blank pages seem to be php memory limit related.
Of course the bad server is the one that has the site that has to go into production!
