Blank pages after moved to new server

[kokotko1337]

Issue: After migration datatables showing blank pages

Problem: moved dokuwiki to another server - moved with RSYNC - same rights and ownership.
Everything working, all plugins only Datatables not.

I tried NOCACHE, and touch but without any success.

Do you have idea what it could be ?

when i delete and table will be shown.

Example of blank page: without SPACE in < datatables> - github format issue only

< datatables>
^ Column A ^ Column B ^ Column C ^
| Row A1 | Row B1 | Row C1 |
| Row A2 | Row B2 | Row C2 |
| Row A2 | Row B2 | Row C3 |
< /datatables>

Example of page which is shown without any issues:

^ Column A ^ Column B ^ Column C ^
| Row A1 | Row B1 | Row C1 |
| Row A2 | Row B2 | Row C2 |
| Row A2 | Row B2 | Row C3 |

You see errors in Browser JSConsole or in Apache error logs?

I'm having the same problem except I just added datatables to a new server. If i refresh the page with no tag it works normally and no JSConsole error is generated. With the tag the attached error is generated and the table looks the same without headers.

Note. The README.md file in the plugin directory says to install the plugin manually in /lib/plugins/icons instead of /lib/plugin/datatables

In the Firefox console I don't find any errors, but nginx error log:

@liszca
Seems you don't have PHP XML module on your server.
Install via package manager, eg.yum install php-xml and restart the webserver.
