TestLink doesn’t show execution tests

by

We have an Apache web server that is used for many things. One of the functions is to run TestLink. One day my colleagues needed to upgrade PHP version from version 5 to version 7. After that some problems occured while using TestLink but most of them was solved already. But one of them still persists.

When Test execution page is opened everything works just fine until a test is selected from test suit tree. When a test is selected then there is a blank/empty space on the right side of the page, there is no specification of a test to execute (preconditions, summary, steps & results, etc.) shown as supposed to.

Additional info:

TestLink version: 1.9.14

MySQL: Ver 14.14 Distrib 5.7.27, for Linux (x86_64)

Apache webserver: Apache/2.4.29 (Ubuntu)

Looking forward for any help

UPDATE:

There is an error message in Apache error logs: 

The log is: PHP fatal error: Uncaught error: Cannot use string offset as an array in /testlink/lib/execute/execSetResults.php:1368
Stack trace:
#0 /testlink/lib/execute/execSetResults.php(89): processTestCase (NULL, Object(stdClass), Object(stdClass), Object(stdClass), Array, Object(tree), Object(testcase), Object(tlAttachmentRepository))
