In this guide, we will explore the cause of this error and offer a straightforward solution to get you back on track.

Understanding the Problem

The Uninitialized string offset error occurs in TBS when there is a problem related to how it interacts with the template you are using. Specifically, this issue may arise when you open a LibreOffice template from a stream, typically done using fopen(). This unintended behavior results in the application displaying error notices rather than your merged values.

Key Symptoms

Error Notices: You'll see messages indicating an uninitialized string offset.

Failed Document Downloads: The merged spreadsheet may not download properly, preventing you from accessing your intended results.

The Solution

Fortunately, resolving this issue is relatively straightforward. Below, we outline clear steps you can take to eliminate the error.

Step 1: Modify the Source Code

The simplest workaround for this bug is to edit the TBS plugin code. You just need to comment out the line of code that is causing the error. Specifically, look for line 1832 in the tbs_plugin_opentbs.php file:

Open the file located under /tinybutstrong-opentbs/ directory.

Navigate to line 1832 and add // at the beginning of that line to comment it out.

Step 2: Update OpenTBS

While the code modification works as a temporary fix, it’s advisable to monitor future updates of the OpenTBS library. The developers are aware of this bug and plan to address it in the next version, so keep an eye out for version 1.10.1. Updating to the latest version will not only resolve this issue but may also include other valuable enhancements and bug fixes.

Conclusion

Encountering the Uninitialized string offset error in TinyButStrong can be frustrating, especially when it disrupts your document merging process. By following the simple workaround of commenting out the problematic line in the TBS plugin and staying updated with new releases, you can effectively resolve this issue and continue utilizing TinyButStrong for your projects.
